Radical as it may sound, it's possible the majority of them are there to serve the American people.
Still, I agree some of them are very unprincipled. That includes most of the 147 GOP congressmen who tried overturning the election, as well as just about all of Trump's opponents in the 2016 primaries (Graham went from calling Trump a "race-baiting xenophobe" to becoming a golfing buddy and Senate slave, and Cruz from someone whose wife and father were insulted by Trump and who encouraged Republicans to "Vote their conscience" before becoming one of Trump's slavish allies in the Senate, to name just two examples).
And shocking and wrong as this may sound, to a lesser degree I consider Arlen Spector (who was very respected across the aisle) to be in a similar category (though a less extreme one). Yes, he was a Republican-turned-Democrat, but that's what makes him slightly untrustworthy, because it seemed toward the end of his tenure that he had absolutely no ideas of his own and just went with what was politically expedient.
Wikipedia explains my point perfectly:
According to the National Journal, Specter voted with Democrats 90% of the time after switching parties, while, as a Republican, he split his votes between both parties. According to FiveThirtyEight, during January–March 2009 Specter voted with the Democrats 58% of the time. Following the support of the stimulus package and the entrance of Pat Toomey in the Republican primary, Specter began to vote 16% with Democrats. When switching to become a Democrat, he voted 69% with his new party initially, until Joe Sestak entered the Democratic primary and Specter started to vote with Democrats 97% of the time.
He came full circle. He went from voting 16% with the Democrats to 90% with Democrats in the span of about twelve months. I'm pretty sure that only a small minority of that was his opinion on issues just suddenly shifting. Even Pat Toomey's campaign noticed and
hammered Specter on it.
