Uhm...did the Democrats care about how "anti-democratic" the Senate was when they held seats in states like North Dakota, Arkansas, and Alaska? Y'know, in the long ago of 2014?
I suppose the argument here is that the rise in polarization since then has helped make it clear how undemocratic the Senate is.
Also, the Democrats had to move pretty strongly to the center to win those seats. Republicans can come very close to a majority even if they run only far-right candidates. This is the main reason our country's polarization is asymmetrical.
If running far-right candidates wins you a majority in the Senate...then are they really "far-right"? Such descriptors are inherently relative to the perceived political center
Why do Democrats think they're the arbiters of what "normal" political positions and conventions are? lol
