February 15 he wrote me again in criticism of the President's invasion of foreign soil. He still believed the Executive had exceeded the limit of his authority. "The provision of the Constitution giving the war-making power to Congress," he insists, "was dictated, as I understand it, by the following reasons: kings had always been involving and impoverishing their people in wars, pretending generally, if not always, that the good of the people was the object. This, our convention understood to be the most oppressive of all kingly oppressions; and they resolved to so frame the Constitution that no one man should hold the power of bringing this oppression upon us. But your view destroys the whole matter, and places our President where kings have always stood." In June the Whigs met in national convention at Philadelphia to nominate a candidate for President. Lincoln attended as a delegate. He advocated the nomination of Taylor because of his belief that he could be elected, and was correspondingly averse to Clay because of the latter's signal defeat in 1844. In a letter from Washington a few days after the convention he predicts the election of "Old Rough." He says: "In my opinion we shall have a most overwhelming glorious triumph. One unmistakable sign is that all the odds and ends are with us--Barn-burners, Native Americans, Tyler-men, disappointed office-seeking Locofocos, and the Lord knows what not.... Taylor's nomination takes the Locos on the blind side. It turns the war thunder against them. The war is now to them the gallows of Haman, which they built for us and on which they are doomed to be hanged themselves."
