you'd have to worry about the potential damage that could be caused by letting an extremist into the position though (things that are not easily fixed an extreme example would be defunding large amounts of social security which could not be easily reversed as the public servants will have been sacked and people reliant on social security will have backslid/ died in the meantime) while Mccarthy seemed like someone the dems could at least work with. (could just be a bad impression though)Maybe they're hoping his replacement will be of the extreme right and thereby hope that swings the pendulum back their way.
edit thanks Maggie5 for mentioning the broken promises
