In moments of frustration, the centrist senator has gone so far as to tell colleagues he may leave the upper chamber before the end of this Congress, or after the 2020 elections.

Senate Democratic Leader Charles Schumer (N.Y.) keeps a close watch on Manchin, and the senators have a good working relationship. While Schumer recognizes that his West Virginia colleague can get exasperated by dysfunction in the Senate, he believes Manchin is content and engaged in his job.

But Manchin says he’s deeply irritated with the lack of bipartisan cooperation on Capitol Hill, where passing bills has largely become an afterthought in the 116th Congress.

Manchin noted supporters in West Virginia are pressing him to run for governor next year, and he’s considering it.
