Address verification is likely only to verify that you're at the correct precinct that you were registered for. You don't have to have a permanent address to vote.
That could be. But, they demand my DL before reciting my name and full address. So...? I have no idea.
All these GOP schemes to prevent voting fraud or reduce costs all seem tailor made to reduce turnout of groups that are presumed to be largely non-GOP.
There is a segment of both parties that feel that people who disagree with them shouldn't have a voice - unfortunately it seems this segment managed to get a lot of control in the GOP while on the left side they mostly get relegated to the loony bin.
Both parties are super guilty of gerrymandering, but "voter fraud" isn't a proportionally important issue and it's been abused by some strategists to implement wide spread voter discrimination.
