Because R and D are meaningless terms anymore, just look at the Wall, the end of Obamacare and the rest of the great accomplishments of the late great Republican congress.
They are branches of the Uniparty, and whichever branch figures out how to work with Trump to accomplish MAGA which is what people actually want, will win. Or would you prefer more Paul Ryan, Jeff Flake, Susan Collins, and McTurd?
I’ve about had it with the GOP.
