I'd hesitate to say liberal politics dominated DC. In the last decade there were only two years where Democrats were able to pass liberal legislation at the federal level: 2008-2010. Even then it was a slog. Republican powers keep pushing the Overton window further and further right and liberals are supposed to just accept it? No, they're going to draw a line and learn to fight back. Only "The Party of No" bears the burden of compromise at this point.
