I've been reading a very detailed history of far-right extremism and racism, the word "communist" has long been associated with civil rights and equality. The protestors in the south shouted, "Go back to Cuba, Nigger lovers."
The code words, "communist", "Marxist" are about race and those who are not comfortable with blacks being equal to whites.
Politics and partisanship are one thing, however the extreme obstructionism in the House and Senate comes from a deeper, darker place--IMO. The tea drinking right has refused to do the work they were hired to do. It's time to put them on notice and replace them with people willing to roll up their sleeves and work.
