Numbers 1, 2, and 3 can all be fixed, and fixing those fix number 4. For gerrymandering, there are plenty of proposals around requiring districts conform to so

Numbers 1, 2, and 3 can all be fixed, and fixing those fix number 4. For gerrymandering, there are plenty of proposals around requiring districts conform to some set of geometric rules. The electoral college issue gets a lot of attention, but the more fundamental problem is first-past-the-post voting. What we really need is approval-based voting (i.e. I approve of candidates A and B; whoever has the most approvals wins). Such would eliminate the incentive to solely vote for the lesser of two evils. The electoral college has a bigger influence than when the Constitution was written due to the even higher concentrations of people in urban centers -- the idea makes sense though, perhaps with some math we can find a compromise. Regardless, FPTP is much more serious. Easy to pass any legislation that changes voting and threatens all the incumbents? Not without a HUGE push, which I don't see happening anytime soon but why not try?
