I'd imagine you and I have different opinions about what constitutes "voter suppression" though.
Well, when it comes to voter
suppression from the govt, I think this works: If they institute new regulations or purposefully sabotage/neglect the system with any belief that it will reduce voter participation from undesired voters. This can mean instituting photo id, or repealing same-day registration primarily for an advantage. Both actions have been seen quite a lot by Republicans in the past 4+ years.
There are legitimate reasons to believe in certain restrictions (felony disenfranchisement, for instance), but I would hope one has a good reason for it. If it is not necessary at all and makes voting more annoying or difficult, then it should be done better so it doesn't make things more difficult. Everyone should have a chance to participate as easily as reasonably possible.
I would certainly love it if America was run by a Democratic president and a liberal Democratic Congressional supermajority, but achieving that by using positions of power to manipulate elections / reduce voter participation is too corrupt and unfair
