Lincoln supported his home state’s law, passed in 1853, forbidding blacks to move to Illinois. The Illinois state constitution, adopted in 1848, called for laws to “effectually prohibit free persons of color from immigrating to and settling in this state.”
To be exact
Are you saying he voted for it in the legislature? Or that he campaigned in support of the law?
The 1848 "law" was the new state constitution. "Support" for the constitution didn't necessarily imply support for all it's provisions, but so far, we've only got your word that he did supported either the 1848 constitution or the 1853 law..
I guess the idea behind all this stuff is that Lincoln isn't what his admirers make him out to be. But neither were the 19th century Southerners that neo-confederates idolize. They were all creatures or their own era, none of whom would measure up to 21st century standards.
For all that, Lincoln was "better" by current standards on racial issues than at least 90% of his countrymen.
