Meh, with regards to eliminating no-excuse absentee voting, it's not that big of a deal if they still keep the same level of in-person early voting. Seeing what Trump did to the USPS this year has definitely made me reconsider the viability of that method of voting.. Not that it's any less useful or safe, but that it's vulnerable to a president who cares so much about winning at any cost that they will literally blow up the country's mail delivery service to even try and gain an advantage.
So if they end absentee voting, people will just shift to in-person early voting. I don't expect much of a partisan disparity in turnout reductions, if there are any.
Yeah, but I'm not sure what they mean by "absentee voting". In Georgia, early in-person voting is legally referred to as "absentee in-person" and mail voting is "absentee by mail". Early in-person voters even have to sign an absentee form when voting via this method...so it's quite possible when they say they're aiming to eliminate "absentee voting at will", they're talking about reverting completely to an Election Day voting system (minus "cause").
It'll be easier to get something like this through the Senate than the House based on sheer partisanship (they have 63% of the seats in the former, while only 58% in the latter), so not surprising it'd start there.
