Is that a picture of Rush Limbaugh at 1:55 as the symbolic image of cynical critics saying that Lincoln only freed the slaves because he was trying to win the war? Lincoln was a republican, Limbaugh is a conservative; many conservative pundits praise Lincoln for the Emancipation Proclamation, and some even like to use it as leverage over liberals in arguments (because it was a republican president who "ended slavery"). I think you'll be hard pressed to find any conservative pundits belittling Lincoln's accomplishments, so it's probably inappropriate to use Limbaugh's face in conjunction with that argument.
