First, we have Virginia. Ambitious governor Glenn Youngkin has to prove he's capable of winning control of the state house if he wants the big-money Republican donors to insert him into the presidential race as a last-minute compromise. (He's got the big Rupert Murdoch stamp of approval!) Via the Washington Post:

Gov. Glenn Youngkin’s elections team has admitted in the run-up to pivotal General Assembly elections that it removed nearly 3,400 qualified voters from the state’s rolls, far higher than the administration’s previous estimate of 270.

Elections officials under Youngkin (R) acknowledged what it called the mistaken removal of about 3,400 voters in a news release Friday — five weeks after early voting began for Nov. 7 General Assembly elections. The outcome will determine the viability of Youngkin’s last-minute presidential prospects and the fate of his conservative legislative agenda, which includes banning most abortions after 15 weeks.

The news release claimed that local registrars had already reinstated all but “approximately 100” of the voters, all of whom had been convicted of felonies, had their voting rights restored and then went on to violate the terms of their probation. The state’s computer software had erroneously counted the probation violations as new felonies that disqualified them from voting, administration officials have said.

Also useful to know: In May, Youngkin pulled Virginia out of the Electronic Registration Information Center (ERIC), the data-sharing group that red and blue states alike relied on for the past decade to keep voter rolls updated before election deniers made it the focus of criticism. Because it involved cooperation with Democratic states, I guess.

Then of course we have Ohio:

Nearly 27,000 inactive Ohio voter registrations were deactivated late last month under a directive from Secretary of State Frank LaRose, state records show.

That figure has been one of the main pieces of information that a Democratic lawmaker and members of the media have been trying to obtain from LaRose’s office about the move, which unlike past voter purges was done with little to no advance public notice after some voters had already begun casting ballots for the Nov. 7 general election.

Each of the 26,666 voter registrations removed on Sept. 28 by elections officials in 85 of Ohio’s 88 counties involved a voter who did not cast a ballot or respond to mailed notices from elections officials over a six-year period. Ohioans can check if their name is among them via a searchable database on the secretary of state’s website.

No matter what state you live in, it's a good ideal to confirm your registration before every election.
