It's generally been more along the fringes, though. Trump is basically making it a centerpiece of his campaign, in a way that I can't recall any other major candidate doing. And not really in any meaningful way either, like "voter ID laws suppress minority votes, we need to get rid of them to help more people be able to vote" or "gerrymandering takes away power from minority zones, districts should be drawn in a more fair manner", but just "If I lose, the other side cheated." And he pushes it at every opportunity now. It's crazy.
