If Biden messes up debate it's 'game over,' former Obama adviser warns

Former Obama adviser and CNN commentator Van Jones said President Biden's chances of winning re-election could be over if he "messes up" the upcoming debate with former President Trump.

"This is the entire election, as far as I’m concerned. The entire world will be watching," Jones told CNN host Jim Acosta on Thursday. "If you are a carbon-based life form, you’re going to be watching. If you’ve got a functioning brain stem, you’re going to be watching."

"Because if Biden goes out there and messes up, it’s game over. If he walks out there and a week later he’s lower in the polls, it’s panic in the party," he continued. "But if he goes in there and he can handle himself against Donald Trump — a runaway train, a locomotive, a raging bull — then this guy deserves another shot to be president, because that is tough."

Acosta wondered if Biden could rebuff GOP attacks questioning his mental acuity if he came out and delivered a strong performance on June 27.

His second guest, legal analyst and former Trump White House counsel Jim Schulz, said one debate wouldn't "make a difference" in eliminating concerns voters have about Biden's age and mental fitness.

"There‘s just too much out there in terms of social media, television, any of the videos, everything that‘s been captured of him walking off-stage, lost. That‘s in people‘s minds and they‘re worried about it," Schulz said. "I don't think there's any turning back on that."
