The article in the New York Evening Post of May 14, two days before the first vote was taken, is a column long. It can only be summarized here.
So long as the court sat, it says, decency forbade the discussion of the issue elsewhere. It characterizes the articles of impeachment in groups and severally, and says Article XI "reads like a jest, in charging solemn official acts of 1868 as done in pursuance of an extreme and excited declaration, made to a crowd, in a political speech almost two years before...." Impertinent issues were constantly pressed upon the court from without. The New York Tribune demanded conviction and removal for breaking the Tenure-of-Office Act, because, it said, the President was guilty of drunkenness, adultery, treason, and murder. The investigation is of a sudden changed in its nature by the advocates of conviction and becomes a matter of politics, and no longer a judicial concern. Senator Wilson leads off by violating an absolutely fundamental principle of the life and law of every free people, i.e., the principle that an accused man shall have the benefit of a doubt, and be believed innocent until proved guilty. Wilson says: "I shall give the benefit of whatever doubts have arisen to perplex and embarrass me to my country rather than to the Chief Magistrate." ... Here was a plain confession that to obtain conviction a "first principle of public law must be sacrificed; that one prominent judge, at least, would condemn the accused, however conscientiously, from other than judicial motives." It describes graphically the pressure brought to bear upon the court and its shameless character, and quotes from the New York Tribune's flagrant attack upon Grimes, Trumbull, and Fessenden, "three of the most honored statesmen and tried patriots in the land." "Thus," it says, "a prominent party organ tries to instigate the passions of the multitude to drive the court to the judgment it desires."
"In a meeting of the Republican Campaign Club on Tuesday evening," it continues, "Charles S. Spencer said that 'as a man of peace and one obedient to the laws, he would advise Senator Trumbull not to show himself on the streets in Chicago during the session of the National Republican Convention, for he feared that the representatives of an indignant people would hang him to the most convenient lamp-post.' And the meeting adopted and ordered to be sent to our Senators in Congress, a resolution, 'that any Senator of the United States elected by the votes of Union Republicans, who at this time blenches and betrays, is infamous, and should be dishonored and execrated while this free Government endures.'"
The following is from the Chicago Tribune, May 14, 1868:
IMPEACHMENT
... The man who demands that each Republican Senator shall blindly vote for conviction upon each article is a madman or a knave. Why a Senator, or any number of Senators, should be at liberty to vote as conscience dictates on any of the articles, provided there be a conviction on some one of them, and not be at liberty to vote conscientiously unless a conviction be secured, is only to be explained upon the theory that the President is expected to be convicted no matter whether Senators think he has been guilty or not. We have protested, and do now protest, against the degradation and prostitution of the Republican party to an exercise of power so revolting that the people will be justified in hurling it from place at the first opportunity. We protest against any warfare by the party or any portion of it against any Senator who may, upon the final vote, feel constrained to vote against conviction upon one, several, or even all of the articles. A conviction by a free and deliberate judgment of an honest court is the only conviction that should ever take place on impeachment; a conviction under any other circumstances will be a fatal error. To denounce such Senators as corrupt, to assail them with contumely and upbraid them with treachery for failing to understand the law in the same light as their assailants, would be unfortunate folly, to call it by the mildest term; and to attempt to drive these Senators out of the party for refusing to commit perjury, as they regard it, would cause a reaction that might prove fatal not only to the supremacy of the Republican party, but to its very existence. Those rash papers which have undertaken to ostracise Senators—men like Trumbull, Sherman, Fessenden, Grimes, Howe, Henderson, Frelinghuysen, Fowler, and others—are but aiding the Copperheads in the dismemberment of our party.
From the Nation, May 14, 1868.
... Can any party afford to treat its leading men as a part of the Republican press has been treating leading Republicans during the last few weeks? Senators of the highest character, who, in being simply honest and in having a mind of their own, render more service to the country than fifty thousand of the windy blatherskites who assail them, have been abused like pickpockets, simply because they chose to think. We have, during the last week, heard language applied to Mr. Fessenden and Mr. Trumbull, for instance, which was fit only for a compound of Benedict Arnold and John Morrissey, and all their colleagues have been warned beforehand, that if they pleaded their oaths as an excuse for differing from anybody who happened to edit a newspaper, they would be held up to execration as knaves and hypocrites. Now, the class of men who are most needed in our politics just now are high-minded, independent men, with their hands clean and souls of their own. Their errors of judgment are worth bearing with for the sake of their character. Yet this class is becoming smaller and smaller, falling more and more into disrepute. The class of roaring, corrupt, ignorant demagogues, who are always on "the right side" with regard to all party measures, grows apace; and, if we are not greatly mistaken, if the Republican party does not make short work with them before long, they will make short work of it....
When it became known that Grimes, Trumbull, and Fessenden would vote not guilty, the pressure from outside was redoubled upon others who had been reckoned doubtful, and especially upon Henderson, Fowler, and Ross.
Even the General Conference of the Methodist Episcopal Church, then in session at Chicago, was called upon to lend a hand, and a motion was made on the 13th of May for an hour of prayer in aid of impeachment. An aged delegate moved to lay that proposal on the table, saying:
My understanding is that impeachment is a judicial proceeding and that Senators are acting under an oath. Are we to pray to the Almighty that they may violate their oaths?
