Wisconsin

we still have same-day voter registration. Go to the polls and you're not in the poll book? Then you just register again. Yes, it's a pain in the ass and you have to have proof of residency (which can often be the registration for the vehicle you drove to the polls), but with a small amount of hassle, you can vote.

Dems also do a huge push to get people to register in advance, check their registration, and vote absentee in advance, etc. If you're worried about your registration in Wisconsin, you can check it and fix it by going to myvote.wi.gov at any time up to 2 weeks before election day.

All this said, I think it's stupid to remove people from the registration database. Everyone must show ID before they can vote, so removing people doesn't prevent fraud. It just creates hassles. That's the GQP trademark, though.
