It's worth marking as well that the voting restrictions are being made particularly in the what, eight, ten swing states that decide the margins on the electoral college? They don't have to be sweeping changes across the nation to change the results for the nation- you just need to make it difficult enough for the disabled, the poor, the minorities, the immunocompromised, busy parents, single parents, (the sorts of people more likely to vote left as a factor to their continued survival), to lack the time or means to register and vote to curve the outcome of the election. If your voting bloc is primarily old white people with unlimited time and the fear of God/existential peril of Communism/ the Mexicans drilled into their heads and you kerjigger it so that that bloc is the only group of people with the time and fervid commitment to vote, you've won. That's why having The Other as an enemy for the Conservative party is so critically important- there's nothing that the party offers them gratis that isn't steeped on a fear or hate that they themselves have cultured, but that's besides the point.
It's a bit like this- assume it was legislated that I needed a REAL ID driver's license to vote. The DMV is half an hour away, there's no public transportation that gets there, they're only open until 4:30, I work 8:30-5:00 every weekday, and they're closed on weekends. It's counting on me getting there during work hours with another form of ID (say, birth certificate, or SSN card), having those in my personal possession (and not, say, with my parents), having a means to get there, being willing to stand in the DMV for half an hour to get that information processed, and having the forty bucks or however much it costs for processing. Fortunately, I am not immunocompromised, I have PTO available to go do this (so my job is not jeopardized if I'm not there), I have my own car, I have my own passport, I have a driver's license already so I can legally drive there, I have no other obligations at home that prevents me from dedicating the 1.5 hours to get the whole thing done, or longer if I had to rely on public transportation, were it available.
Knock out any of those pegs and I'm no longer able to vote. All by no decision of my own, save that I wish to continue surviving. This is why voting by mail was such a boon for the common voter, and why republicans so viciously tried (and succeeded in places) to clamp down on our capacity to vote by mail in the future, and why the discussion around the Jan 6th Insurrection were around 'fraudulent' mail-in ballots.
