Joe Manchin is one sorry motherf***er. Congratulations on selling your soul to win an election.
What else would you have expected? At this point, it's pretty clear to me that the Democratic Party wants all of its candidates to be in step with every element of the national agenda. Such an agenda will not help them recover the ground that they have lost in places like West Virginia.
Then what is the point having a Democrat (vs letting a Republican win) if the end result vote is going to be the same almost 100% of the time?
