Q has satisfied my doubts about "De Day ob Liberty's Comin'" (1862) on another thread.

But the word "whitey" isn't in it.

The story of Lincoln and habeas corpus is a complicated one. Of questionable legality in 1861, the suspension was made legal by the U.S. Congress in 1863 "for the duration of the present rebellion" only. It provided among other things for the release of political prisoners (i.e., Southern sympathizers). The U.S. Supreme Court judged the Congressional legislation Constitutional but limited its application further.

Had Lincoln done "so many illegal things" of any consequence, I suspect the Democrats would have tried to impeach him. Most of them opposed the war anyway.
