During the Clinton years the Party PURGED any and everyone who didn’t tow the line, drove the blue dogs out, and started to require purity....
A few still exist here and there, but they have no say.. The party has been the party of ideological purity of global leftism since the end of the Clinton years...
They still played the game of pretending they weren’t at election time up until Trump... Trump, instead of being polite, simply called them on it... Hillary’s “unexpected” loss caused them to drop the mask wholesale... though still some try to pretend at election time, then go govern far left, the ploy is working less and less.... Trump has exposed them.
They were purging non-Socialists under FDR in the 1930s.
