FPTP by itself might not be so bad, but combine it with primaries and you’ve got a recipe for extremism and scorched earth politics. Now throw in gerrymandering and we’ve got a wildly unrepresentative election process.

Don’t get me started on the electoral college either. I’m for a national popular vote.
