The Democrats’ problem is that their supporters are better at sorting themselves into geographically distinct clusters, i.e. cities. You don’t get more Democratic representation for a 90% win than a 52% one. And gerrymandering is a bipartisan endeavour, whichever party is in power during redistricting gerrymanders, that’s just American politics. As far as the electoral college goes no one is making any effort at reform because no one cares unless it’s their ox that’s been gored. US presidential elections go by electoral college vote so that’s how candidates campaign. If it was by popular vote a lot more Republicans would bother voting in California and a lot more Democrats in Utah. There’s no actual constituency for reform, just the whining of losers. When the Democrats next take the White House there will be no talk of reforming the Electoral College.
