The Georgia Law massively increased voter access vs. pre-pandemic rules. It slightly rolled back some of adjustments that were made for voting in a pandemic. We went from no drop boxes before the pandemic, to 24 hour drop boxes for the pandemic, to now having permanent drop boxes, but not outside 24 hours. More early voting, more weekend voting, etc. It's like the 10th most open access election law in the country.
I agree there hasn't been election fraud on the level to tip elections. However, comparing fraud levels against much, much more restrictive election rules pre-pandemic is only so helpful.
If we're moving to a system that's mostly absentee, etc, there is nothing wrong with reasonable security to be able to certify legitimate elections. It's been scientifically proven that voting "restrictions" or expanded access have little effect on turnout. It isn't hard to vote, it's never been that hard to vote, and people that want to vote do vote. The rhetoric of "suppressing the vote" is just that, rhetoric. Having drop boxes available 16 hours a day instead of 24 will not materially suppress black votes or anyone's votes.
However, having a modicum of verification in place DOES eliminate the cover for bullshit opportunists to call "fraud" every time the election doesn't go that way, which has now happened in Georgia from each party in successive cycles, with no evidence.
That's the purpose isn't to stop non-existent fraud happening under our old election system, it's to prevent potential fraud with much broader access and much less in-person voting, and most of all it's to remove the space for sore losers to call fraud every election.
