Even though Sanders swept WV in the 2016 primary, exit polls from back then indicated that among Democratic primary voters, 33% of them planned to vote for Trump against Sanders in the GE (36% of them for Trump against Clinton), which is a clear indication that Sanders wouldn't have been favored against Trump in the GE (remember that Bush & McCain each won 30% of Democrats in WV in 2004 & 2008, respectively).
I know, you know, we all know, but red rose Twitter will just keep posting "HE WON EVERY COUNTY" and will put clap emojis between the words if we still disagree.
