Why is it that every time the left loses a big one, the proposals about how the nature of American Democracy need to change come out of the woodwork?
Are you unaware of the proposals by Republican legislatures to hand electoral votes to the Republican nominee based on gerrymandered districts?
Most countries get by with one chamber just fine, so there is no reason for this country to have two.
No different from the Democrats coming up with the national popular vote compact after 2000. There's quite a bit of daylight between that and abolishing 1/2 of a branch of government.
Not that going to the House alone would help the Dems much.
