YOU really need to think this through.
You don't "update" the voting rolls by going through and indiscriminately delete names from the list, 6 weeks before the election. There's a process of identifying names for deletion; notifying the people about to be deleted and giving them a waiting period for a response; sending a final notice of the deletion, with a similar waiting period; and finally deleting the name.
The "indiscriminate" deletion of names just prior to the election was generally done for poor and minority neighbourhoods, and almost never in dependably Republican strongholds. This, combined with the reduction in the number of polling stations in dependably Democratic stronghold, is the very definition of "voter suppression".
YOU really need to think all of this through without your hatred of Democrats clouding your analytical thinking.
The USA has been using mail in balloting since the Civil War without ANY problems with cheating. The Republican Party has been PROMOTING the use of mail in ballots in red states as a means to get their mostly older voters to vote in elections, and up until 2020, Republicans were the overwhelmingly majority of mail-in voters.
In the meantime, Republicans in red states have been closing polling stations in poor and/or minority neighbourhoods since the Republicans refused to re-authorize portions of the Voting Rights Act. More than 1.200 polling stations have been closed or moved to areas not serviced by public transit, in mostly Southern Red States. Making it harder and harder for the working poor to vote
States across the American South have closed nearly 1,200 polling places since the Supreme Court weakened a landmark voting-discrimination law in 2013, according to a report released by a civil-rights group on Tuesday.

But in 2020, the Democrats discovered mail-in voting, and suddenly, Republicans are claiming that something they've been promoting for 150 years is "unsafe" and rife with fraud. And you fell for it.
Stop believing the people who are lying to you.
