I don’t know what Joe Manchin would be worried about. After this election, it’s been shown that Democrats will be elected in perpetuity. Look at the Obamacare vote - there were no repercussions. There might have been a blip in Democrat elections but they came roaring back by controlling all of the federal government. Pretty good for a party that’s despised by more than half the country.
Because they probably cheated in the mid-term 2018 election as well.
Remember all those congressional seats that had the R up all night and then as time went on the D candidate pulled it out?
