It's actually even more than that. The list of people who have voted is available for public inspection on election day itself. In close races, campaigns will send people out to review the list(s), note which of their likely voters haven't voted yet, then call them to offer a ride or otherwise help them get to the polls so they can vote. It's not that common at the presidential level, but for city council or the like, it can make a real difference.

Do you have a source for this? I tried to find the laws on this but don't really see anything that discusses accessing a list of who voted during an election. I feel this this should be inaccessible until after the election.

Looks like it depends on the state: https://www.rcfp.org/open-government-sections/i-election-rec...

Most common is allowing the inspection of the list of absentee requestors, like in North Carolina: The chief election judge of each precinct is required to post one copy of the precinct absentee ballot list “in a conspicuous location in the voting place.”

That said, there are other states that do not allow this, so it's less widespread than I originally thought, and when it is allowed, it's usually either just the absentee requestors, or the list is made available after the election, not during. Sorry.
