A third party presidential bid by Democratic Senator Joe Manchin of West Virginia could have a major impact on the 2024 race and siphon votes away from President Joe Biden.

The senator was asked about a potential presidential run during a No Labels forum at St. Anselm College in New Hampshire and didn't rejected the possibility that he could run against Biden in 2024.

That could be a political headache for the president amid concerns that a serious third party challenger could siphon votes away from him, potentially leading to victory for the Republican candidate.

Joe Manchin's 2024 Flirtation Gives Joe Biden a Major Headache

Manchin's flirtation with a 2024 presidential bid could have a major impact on the race and siphon votes away from the president.

Former President Donald Trump remains the favorite to win the GOP's 2024 presidential nomination and No Labels has said it will field presidential and vice presidential candidates if Trump and Biden are both on the ballot again.

Manchin dismissed the idea that he could act as a spoiler candidate.

"I've never been in any race I've ever spoiled. I've been in races to win," the senator said on Monday. "And if I get in a race, I'm going to win."

On Monday night, Manchin told CNN's Kaitlan Collins: "I haven't made any decision, nor will I make a decision until the end of the year."

Manchin, who represents West Virginia, is considered a moderate or conservative Democrat and he also told Collins that Biden has been "been pushed too far left" but "has the strength to fight back."

Former North Carolina Governor Pat McCrory, who is national co-chair of No Labels, said on Monday: "We will present a president and vice president candidate on a No Labels ticket if Biden and Trump are on track to win their parties' nominations."

"We plan to do that. But only if we see we have an opportunity to win," he said. The group will reportedly make a decision after Super Tuesday when there should be a clear indication of who the Republican and Democratic candidates will be.

Manchin is up for re-election in the Senate in 2024 and could be in for a tough race, with West Virginia's Republican Governor Jim Justice challenging him for his seat.

While it may be too early to imagine a Manchin presidential ticket, political scientists who spoke to Newsweek said the possibility would be concerning for Biden.

An Opaque Candidacy Manchin's motivations in not ruling out a presidential bid could have more to do with his position in the Senate and the Democratic Party than a genuine desire to run.

"Joe Manchin remains a conundrum wrapped in an enigma for political strategists. While on the surface he seems a straight shooter in answering every question thrown at him, he does so in a way that often teases and rarely delivers full clarity," said Mark Shanahan, an associate professor in politics at the University of Surrey in the U.K., co-editor of The Trump Presidency: From Campaign Trail to World Stage.
