Several members of the House who had been elected as anti-Nebraska Democrats voted for Lincoln and a few for Shields. The vote for Trumbull consisted of Senators Palmer, Judd, and Cook and Representatives Baker and Allen.
On the second vote, Lincoln had 43 and Trumbull 6, and there were no other changes. A third roll-call resulted like the second. Thereupon Judge Logan moved an adjournment, but this was voted down by 42 to 56. On the fourth call, Lincoln's vote fell to 38 and Trumbull's rose to 11. On the sixth, Lincoln lost two more, and Trumbull dropped to 8.
It now became apparent by the commotion on the Democratic side of the chamber that a flank movement was taking place. There had been a rumor on the streets that if the reëlection of Shields was found to be impossible, the Democrats would change to Governor Matteson, under the belief that since he had never committed himself to the Nebraska Bill he would be able, by reason of personal and social attachments, to win the votes of several anti-Nebraska Democrats who had not voted for Shields. This scheme was developed on the seventh call, which resulted as follows:
| Matteson | 44 |
| Lincoln | 38 |
| Trumbull | 9 |
| Scattering | 7 |
| — | |
| Total | 98 |
On the eighth call, Matteson gained two votes, Lincoln fell to 27, and Trumbull received 18. On the ninth and tenth, Matteson had 47, Lincoln dropped to 15, and Trumbull rose to 35.
The excitement deepened, for it was believed that the next vote would be decisive. Matteson wanted only three of a majority, and the only way to prevent it was to turn Lincoln's fifteen to Trumbull, or Trumbull's thirty-five to Lincoln. Obviously the former was the only safe move, for none of Lincoln's men would go to Matteson in any kind of shuffle, whereas three of Trumbull's men might easily be lost if an attempt were made to transfer them to the Whig leader. Lincoln was the first to see the imminent danger and the first to apply the remedy. In fact he was the only one who could have done so, since the fifteen supporters who still clung to him would never have left him except at his own request. He now besought his friends to vote for Trumbull. Some natural tears were shed by Judge Logan when he yielded to the appeal. He said that the demands of principle were superior to those of personal attachment, and he transferred his vote to Trumbull. All of the remaining fourteen followed his example, and there was a gain of one vote that had been previously cast for Archibald Williams. So the tenth and final roll-call gave Trumbull fifty-one votes, and Matteson forty-seven. One member still voted for Williams and one did not vote at all. Thus the one hundred members of the joint convention were accounted for, and Trumbull became Senator by a majority of one.
This result astounded the Democrats. They were more disappointed by it than they would have been by the election of Lincoln. They regarded Trumbull as an arch traitor. That he and his fellow traitors Palmer, Judd, and Cook should have carried off the great prize was an unexpected dose; but they did not know how bitter it was until Trumbull took his seat in the Senate and opened fire on the Nebraska Bill.
Lincoln took his defeat in good part. Later in the evening there was a reception given at the house of Mr. Ninian Edwards, whose wife was a sister of Mrs. Lincoln. He had been much interested in Lincoln's success and was greatly surprised to hear, just before the guests began to arrive, that Trumbull had been elected. He and his family were easily reconciled to the result, however, since Mrs. Trumbull had been from girlhood a favorite among them. When she and Trumbull arrived, they were naturally the centre of attraction. Mr. and Mrs. Lincoln came in a little later. The hostess and her daughters greeted them most cordially, saying that they had wished for his success, and that while he must be disappointed, yet he should bear in mind that his principles had won. Mr. Lincoln smiled, moved toward the newly elected Senator, and saying, "Not too disappointed to congratulate my friend Trumbull," warmly shook his hand.
Lincoln's account of this election, in a letter to Hon. E. B. Washburne, concludes by saying:
