Sen. Joe Manchin (D-W.Va.) on Monday had an abrupt and brief response to the idea of campaigning with President Obama.

"No," Manchin said on MSNBC's "Morning Joe," cutting off a question about the prospect.

The instant response caught the hosts off-guard for a moment, as most Democrats in similar situations (red states) offer a somewhat more nuanced response.

Manchin also talked about the idea that he might leave the Senate in 2016 to run for his old office of governor. The senator, who often ranks as the most conservative in his caucus, said he likes the idea of being a U.S. senator and carrying on the tradition of former senator Robert Byrd (D-W.Va.), but that actually serving has proven frustrating.

"I've not been there when anything's worked," Manchin said of the upper chamber.

Manchin, 66, added that he needs to think about where he can have the most impact in his remaining years of public service.

"But if the leaders and everybody doesn't work together and try to make something happen, and it's just going to be stalemate as it's been. And I've got to rethink it, too," Manchin said. "I mean, I'm not a spring chicken."
