Democrats probably should do something about First Past The Post voting in states they control then.
Literally the nation on the line, why *wouldn't * you have multiple political parties competing to beat the Republicans? Why wouldn't you want more then one chance to defeat the republicans?
The only logical answer is that having the nation fall to authoritarianism is preferable to Democrats then having to compete for your vote.
Party over country, vain in every way possible, arrogance that runs so deep it is a festering mortal wound.
