A reasonable response although I disagree w. your first paragraph. I personally think if a person has served their time in jail, then their voting rights should be restored upon being being set free. To me, the punishment is the jail time and I don't see the point or the fairness in preventing someone from voting for the next 5/10/20 years for having a drug conviction or whatever. Obviously, if their crime had to do with some sort of voter fraud, I would feel differently. Additionally, a higher percentage of those incarcerated are minorities who tend to vote democratic more often, so I think if would be naive to think that isn't one of the reasons form any many states moving to that.
I agree that sometimes there are logical reasons for moving polling stations, but there are other times when the motive is to keep people from the polls. Google what they did in Garden City Kansas a few years ago. Lack of polling stations in crowded areas is complete and total bullshit. Forcing people to stand hours in line to vote is going to keep the turnout lower. I live in the suburbs and it literally takes me 10 minutes to get in there, vote and get out. It should be the same across the board.
If ballot harvesting is a big issue, then it needs to be absolutely be addressed. As does gerrymandering.
