I was considering posting this in General Questions, but settled on Great Debates because I think it will inevitably turn into a political argument.
It seems to be there is a genuine asymmetry between the two parties on voter suppression. This doesn’t seem to be a case of “both sides do it.” Let’s keep this discussion confined to the 21st century. I know the Southern Democrats during Jim Crow suppressed black votes, and blacks tended to vote Republican back then. But I don’t think reaching back that far into the past is relevant for discussing today’s political climate.
I’m not aware of any systemic attempts by the Democrats to make it more difficult for Republicans to vote, even when that might have been to their advantage. When the Tea Party backlash happened in 2010, did the Democrats try to suppress rural white (Republican) votes to maintain their power?
