Former Vice President Joe Biden once again disappointed Democrats hoping to hear there might be another presidential bid in his future.

"Guys, I'm not running," Biden said in a speech to a New Hampshire Democrats on Sunday, who booed his decision not to run in 2020.

The former vice president was joined by New Hampshire Senators Jeanne Shaheen and Maggie Hassan at the Democratic Party dinner in Manchester to celebrate the United States' first all-female, all-Democratic congressional delegation.

"When I got asked to speak, I knew it was going to cause speculation," Biden said.

Leaders who make early political visits to New Hampshire, the nation's first state to vote in the presidential primaries, often draw public attention and raise questions about their potential candidacy.

Former 2016 Republican presidential candidate John Kasich, for example, has not ruled out a presidential campaign for 2020, and recently made a stop in the Granite State to tour his new book "Two Paths: America Divided or United."

Later, at a breakfast in Washington, hosted by The Christian Science Monitor, Kasich was asked about a presidential run in 2020.

"It's unlikely, but I don't know what the future is going to bring for me, or what responsibility or obligation I might feel," Kasich said. "You don't ever say no to anything in life," he later added.

Biden, on the other hand, spoke instead of his plans to raise money for Democratic campaigns at varying levels of government, restoring decorum to the political process and balancing progressive idealism with Democratic appeal among working-class voters.

"I know it seems like we're hopelessly divided," Biden said. "I know it feels like we're hopelessly stuck in a political death match and we can't figure out how to get out of it, but we are better than that. I've always believed that we're strongest when we act as one America."
