I'd say around 30%.
You really underestimate just how racist and evil cacs are
You really think only 30 percent of cacs would vote to reinstate slavery

I'm betting atleast 80 percent of cac republican voters would vote for reinstation and then you
have about 20 percent closet racist centrist (Joe biden voters) who would also vote in favour, that's probably
If you think those cacs living in rural and surbubian areas of Wiscosin,Missouri,Michigan, upstate NY, Orange county etc aren't gonna join their republican cacs in the south to vote in favour then you are really naive.
