The first session of the twenty-eighth Congress, which convened December 1843, exhibited in its political complexion, serious losses in the Whig following. The Democratic candidate for Speaker of the House of Representatives, was elected over the Whig candidate—the vote standing 128 to 59. Thus an adverse majority of more than two to one was the result to the Whig party at the first election after the extra session of 1841. The President’s message referred to the treaty which had lately been concluded with Great Britain relative to the northwestern territory extending to the Columbia river, including Oregon and settling the boundary lines; and also to a pending treaty with Texas for her annexation to the United States; and concluded with a recommendation for the establishment of a paper currency to be issued and controlled by the Federal government.

For more than a year before the meeting of the Democratic Presidential Convention in Baltimore, in May 1844, it was evident to leading Democrats that Martin Van Buren was the choice of the party. To overcome this popular current and turn the tide in favor of Mr. Calhoun, who desired the nomination, resort was had to the pending question of the annexation of Texas. Mr. Van Buren was known to be against it, and Mr. Calhoun for it. To gain time, the meeting of the convention was postponed from December previous, which had been the usual time for holding such elections, until the following May. The convention met, and consisted of two hundred and sixty-six delegates, a decided majority of whom were for Mr. Van Buren, and cast their votes accordingly on the first ballot. But a chairman had been selected, who was adverse to his nomination; and aided by a rule adopted by the convention, which required a concurrence of two-thirds to effect a nomination, the opponents of Mr. Van Buren were able to accomplish his defeat. Mr. Calhoun had, before the meeting of the convention, made known his determination, in a public address, not to suffer his name to go before that assemblage as a candidate for the presidency, and stated his reasons for so doing, which were founded mainly on the manner in which the convention was constituted; his objections being to the mode of choosing delegates, and the manner of their giving in their votes—he contending for district elections, and the delegates to vote individually. South Carolina was not represented in the convention. After the first ballot Mr. Van Buren’s vote sensibly decreased, until finally, Mr. James K. Polk, who was a candidate for the Vice-Presidency, was brought forward and nominated unanimously for the chief office. Mr. Geo. M. Dallas was chosen as his colleague for the Vice-Presidency. The nomination of these gentlemen, neither of whom had been mentioned until late in the proceedings of the convention, for the offices for which they were finally nominated, was a genuine surprise to the country. No voice in favor of it had been heard; and no visible sign in the political horizon had announced it.

The Whig convention nominated Henry Clay, for President; and Theodore Frelinghuysen for Vice-President.

The main issues in the election which ensued, were mainly the party ones of Whig and Democrat, modified by the tariff and Texas questions. It resulted in the choice of the Democratic candidates, who received 170 electoral votes as against 105 for their opponents; the popular majority for the Democrats being 238,284, in a total vote of 2,834,108. Mr. Clay received a larger popular vote than had been given at the previous election for the Whig candidate, showing that he would have been elected had he then been the nominee of his party; though the popular vote at this election was largely increased over that of 1840. It is conceded that the 36 electoral votes of New York State gave the election to Mr. Polk. It was carried by a bare majority; due entirely to the Gubernatorial candidacy of Mr. Silas Wright, who had been mentioned for the vice-presidential nomination in connection with Mr. Van Buren, but who declined it after the sacrifice of his friend and colleague; and resigning his seat in the Senate, became a candidate for Governor of New York. The election being held at the same time as that for president, his name and popularity brought to the presidential ticket more than enough votes to make the majority that gave the electoral vote of the State to the Democrats.

President Tyler’s annual and last message to Congress, in December 1844, contained, (as did that of the previous year) an elaborate paragraph on the subject of Texas and Mexico; the idea being the annexation of the former to the Union, and the assumption of her causes of grievance against the latter; and a treaty was pending to accomplish these objects. The scheme for the annexation of Texas was framed with a double aspect—one looking to the then pending presidential election, the other to the separation of the Southern States; and as soon as the rejection of the treaty was foreseen, and the nominating convention had acted, the disunion aspect manifested itself over many of the Southern States—beginning with South Carolina. Before the end of May, a great meeting took place at Ashley, in that State, to combine the slave States in a convention to unite the Southern States to Texas, if Texas should not be received into the Union; and to invite the President to convene Congress to arrange the terms of the dissolution of the Union if the rejection of the annexation should be persevered in. Responsive resolutions were adopted in several States, and meetings held. The opposition manifested, brought the movement to a stand, and suppressed the disunion scheme for the time being—only to lie in wait for future occasions. But it was not before the people only that this scheme for a Southern convention with a view to the secession of the slave States was a matter of discussion; it was the subject of debate in the Senate; and there it was further disclosed that the design of the secessionists was to extend the new Southern republic to the Californias.

The treaty of annexation was supported by all the power of the administration, but failed; and it was rejected by the Senate by a two-thirds vote against it. Following this, a joint resolution was early brought into the House of Representatives for the admission of Texas as a State of the Union, by legislative action; it passed the House by a fair majority, but met with opposition in the Senate unless coupled with a proviso for negotiation and treaty, as a condition precedent. A bill authorizing the President and a commissioner to be appointed to agree upon the terms and conditions of said admission, the question of slavery within its limits, its debts, the fixing of boundaries, and the cession of territory, was coupled or united with the resolution; and in this shape it was finally agreed to, and became a law, with the concurrence of the President, March 3, 1845. Texas was then in a state of war with Mexico, though at that precise point of time an armistice had been agreed upon, looking to a treaty of peace. The House resolution was for an unqualified admission of the State; the Senate amendment or bill was for negotiation; and the bill actually passed would not have been concurred in except on the understanding that the incoming President (whose term began March 4, 1845, and who was favorable to negotiation) would act under the bill, and appoint commissioners accordingly.

Contrary to all expectation, the outgoing President, on the last day of his term, at the instigation of his Secretary of State, Mr. Calhoun, assumed the execution of the act providing for the admission of Texas—adopted the legislative clause—and sent out a special messenger with instructions. The danger of this had been foreseen, and suggested in the Senate; but close friends of Mr. Calhoun, speaking for the administration, and replying to the suggestion, indignantly denied it for them, and declared that they would not have the “audacity” to so violate the spirit and intent of the act, or so encroach upon the rights of the new President. These statements from the friends of the Secretary and President that the plan by negotiation would be adopted, quieted the apprehension of those Senators opposed to legislative annexation or admission, and thus secured their votes, without which the bill would have failed of a majority. Thus was Texas incorporated into the Union. The legislative proposition sent by Mr. Tyler was accepted: Texas became incorporated with the United States, and in consequence the state of war was established between the United States and Mexico; it only being a question of time and chance when the armistice should end and hostilities begin. Although Mr. Calhoun was not in favor of war with Mexico—he believing that a money payment would settle the differences with that country—the admission of Texas into the Union under the legislative annexation clause of the statute, was really his act and not that of the President’s; and he was, in consequence, afterwards openly charged in the Senate with being the real author of the war which followed.

The administration of President Polk opened March 4, 1845; and on the same day, the Senate being convened for the purpose, the cabinet ministers were nominated and confirmed. In December following the 29th Congress was organized. The House of Representatives, being largely Democratic, elected the Speaker, by a vote of 120, against 70 for the Whig candidate. At this session the “American” party—a new political organization—first made its appearance in the National councils, having elected six members of the House of Representatives, four from New York and two from Pennsylvania. The President’s first annual message had for its chief topic, the admission of Texas, then accomplished, and the consequent dissatisfaction of Mexico; and referring to the preparations on the part of the latter with the apparent intention of declaring war on the United States, either by an open declaration, or by invading Texas. The message also stated causes which would justify this government in taking the initiative in declaring war—mainly the non-compliance by Mexico with the terms of the treaty of indemnity of April 11, 1839, entered into between that State and this government relative to injuries to American citizens during the previous eight years. He also referred to the fact of a minister having been sent to Mexico to endeavor to bring about a settlement of the differences between the nations, without a resort to hostilities. The message concluded with a reference to the negotiations with Great Britain relative to the Oregon boundary; a statement of the finances and the public debt, showing the latter to be slightly in excess of seventeen millions; and a recommendation for a revision of the tariff, with a view to revenue as the object, with protection to home industry as the incident.

At this session of Congress, the States of Florida and Iowa were admitted into the Union; the former permitting slavery within its borders, the latter denying it. Long before this, the free and the slave States were equal in number, and the practice had grown up—from a feeling of jealousy and policy to keep them evenly balanced—of admitting one State of each character at the same time. Numerically the free and the slave States were thus kept even: in political power a vast inequality was going on—the increase of population being so much greater in the northern than in the southern region.

The Ashburton treaty of 1842 omitted to define the boundary line, and permitted, or rather did not prohibit, the joint occupation of Oregon by British and American settlers. This had been a subject of dispute for many years. The country on the Columbia River had been claimed by both. Under previous treaties the American northern boundary extended “to the latitude of 49 degrees north of the equator, and along that parallel indefinitely to the west.” Attempts were made in 1842 and continuing since to 1846, to settle this boundary line, by treaty with Great Britain. It had been assumed that we had a dividing line, made by previous treaty, along the parallel of 54 degrees 40 minutes from the sea to the Rocky mountains. The subject so much absorbed public attention, that the Democratic National convention of 1844 in its platform of principles declared for that boundary line, or war as the consequence. It became known as the 54–40 plank, and was a canon of political faith. The negotiations between the governments were resumed in August, 1844. The Secretary of State, Mr. Calhoun, proposed a line along the parallel of 49 degrees of north latitude to the summit of the Rocky mountains and continuing that line thence to the Pacific Ocean; and he made this proposition notwithstanding the fact that the Democratic party—to which he belonged—were then in a high state of exultation for the boundary of 54 degrees 40 minutes, and the presidential canvass, on the Democratic side, was raging upon that cry.
