It's also an untrue post: This...
to bad he disagreed with progressives,,,,,that was the end of his political career...
Makes it sound as if poor Manchin was driven out of office by those evil Progressives. Not so. He dabbled with the idea of running for the presidency as a third party candidate, and then abandoned it.
In addition, he's 76. He probably thinks he's old enough to retire. But had he chosen to run for the senate again as a Dem, or even as a third party candidate, he'd probably have won.
