Newt Gingrich made those remarks Thursday on Fox News' "Hannity," criticizing the former vice president and saying that he is an "incompetent" leader and that "none of his programs work."
"The challenge you've got ... is [that] there are Americans for whom facts matter. And, there are Americans for whom emotions matter," Gingrich a former Republican speaker of the U.S. House representing Georgia, said.
"The emotional Americans are going to go, 'But Uncle Joe means so well'," Gingrich said. "If this is a race about facts, Biden might as well go home this evening."
Host Sean Hannity played a clip from a Biden campaign ad -- which was broadcast in Spanish.
"Our politics have become so petty, so negative, so cruel, it's tearing us apart and dragging us down," the narrator in the ad says. "Now, Joe Biden is running for president and as president, he will unite us all."
Gingrich remarked that the "people who like winning are going to end up voting for [President Donald] Trump and the Republicans."
He said he suspected that if Biden had not had former President Barack Obama on the ticket, the former U.S. senator from Delaware "wouldn't have been vice president."
Biden joined the crowded Democratic presidential field in late April.
"The core values of this nation, our standing in the world, our very democracy, everything that has made America -- America -- is at stake. That’s why today I’m announcing my candidacy for president of the United States," Biden tweeted in announcing his presidential bid.
