Arizona Democratic Party has passed a resolution pledging a vote of NO CONFIDENCE in @KyrstenSinema

70. Unfortunately, It Does Not

There are no provisions in the US Constitution for recalling anyone elected to federal office. We'd need a constitutional amendment for that, and we know what the likelihood of that happening is (snowball, meet hellfire). The only ways to get rid of any federal level office holder are to 1) primary that person out, 2) beat them at the main election, 3) they die in office, or 4) they are kicked out by their colleagues for corruption.

#1 and 2 happen, but not often due to the power of incumbency. The incumbent wins 90% of the time, according to the guys at Electoral-Vote.com. The overall attitude people take seems to be that they hate Congress in general, detest the "other party" specifically, but "their guy" is "doing OK". (This assumes that you're in the same party as the incumbent, of course.)
#3, I don't know what the stats are on.
#4 is extremely rare. Not many congress critters have ever been kicked out.
