Former senator Joe Lieberman knows better than most the impact third-party bids can have on presidential elections. His 2000 Democratic campaign for vice president fell just 537 Florida votes short of victory, in a state where Ralph Nader, the liberal activist and Green Party nominee, won more than 97,000 votes.

But that didn’t stop the Connecticut Democrat turned independent from joining a meeting Thursday in support of plans by the centrist group No Labels to get presidential ballot lines in all 50 states for 2024. The group calls its effort an “insurance policy” against the major parties nominating two “unacceptable” candidates next year.

Asked if President Biden, his former Senate colleague, would be unacceptable, Lieberman said the answer was uncertain.

“No decision has been made on any of that. But we’re putting ourselves in a position,” Lieberman said. “You know, it might be that we will take our common-sense, moderate, independent platform to him and the Republican candidate and see which one of them is willing to commit to it. And that could lead to, in my opinion, a No Labels endorsement.”
