How does he do it?
He even detected that Lincoln "championed his corrupt Whig economic agenda in virtually every one of the Lincoln Douglas debates," again without any evidence even from the transcripts of the debates.

Perhaps the case lacks definitive verification, but it is an enormous stretch to say that there is no evidence of any kind. There is Lincoln's well-known deep admiration for Clay; there is his loyal membership in the Whig party until its demise. There are Lincoln's several apparantly bitter references to Jackson's action in the matter of the national bank. Finally, there is the fact that, upon assuming the presidency and not being hampered by Southerners in the Congress, Lincoln immediately acted to implement the several principle features of the Whig economic program.
