I don’t think WV people as a whole would ever seriously considering reprimanding Manchin for much of anything.
I don't know, I use to think the same thing. But in the thirty years I've lived in West Virginia, it's gone from deep blue to light red, and getting more red every election. The legislature may very well tip Republican for the first time since 1928 next election (the democrats only control it by four seats after 2012 (54D-46R). When I moved here in 1983 it was (87D-13R)!! It has gotten so the only way a democrat like Manchin can win is to masquerade as a conservative Republican. He ran as pro-gun, pro-life, anti-gay marriage.
