Senator Joe Manchin is a Democrat but he serves in the red state of West Virginia. He recently announced that he is going to run again and at the same time, issued a warning to his leftward drifting party.
From the New York Times via Hot Ar:
Senator Joe Manchin III of West Virginia told colleagues on Tuesday that he intended to run for re-election this year after all, ending an anxiety-making flirtation with retirement and easing Democratic fears that the most conservative Democrat in the Senate was about to effectively hand his seat to a Republican.
In an interview, Mr. Manchin said he repeatedly expressed his frustration to Senator Chuck Schumer of New York, the Democratic leader, and other colleagues, telling them that “this place sucks,” before finally signaling Tuesday morning to Mr. Schumer’s aides that he would file his re-election paperwork before West Virginia’s deadline on Saturday. …
“I’ve said this point blank: If people like me can’t win from red states, you’ll be in the minority the rest of your life,” Mr. Manchin said about his conversations with other Democrats about the need to tolerate more moderate lawmakers.
This is not what the Democratic party base wants to hear right now but it’s absolutely true. If they keep pushing to the hard left, they will become a fringe party.
