What question? Would they vote for Dems? Probably, that would be my guess but that doesn't even begin to prove your (or the president's) claim that there are literally millions of them voting. Also, my state is an extremely red state and they check my ID every time I vote and I'm surprised every time that they don't also ask for a blood sample to prove it's me, even though I've been voting at the same place with most of the same people for over 15 years and the pastor (it's at a church) knows me because I was one of his wife's favorite instructors from when she got her degree (she told him about me, I did not bring it up).
My question is, don't you think all red states or even potentially red states check voter ID pretty closely? If anyone were going to cheat in this way it would be a blue state, like Cali, MI, or NY, states a Repub is not nearly as likely to win anyway. Be honest there isn't a speck of evidence of the kind of wholesale voter fraud the president claims exists, just another Alex Jones type conspiracy. At what point do you make those people prove their claims? And if we are honest at all, it's impossible to deny the steps Repubs have take to purge voter roles, move or eliminate places where likely Dem voters can either register or get IDs, and other illegal (in many states anyway) voter supression. So be honest, is it the Dems attempts at illegal voting you dislike (which I still have yet to actually see evidence of, other than some claims by conservative groups that are supposedly honest) or Repub attempts at voter supression for which you can find legitimate evidence all over the place (if you look)?? Is it illegal attempts to influence elections that bothers you, or just illegal Dem attempts to influence it?
