“She’s exposed herself so little to voters,” Bedford told Your World with Neil Cavuto. “She has raised the stakes for this [debate] because this is the one chance that she’s really given voters to see how she performs when she’s off the teleprompter, and if she blows that or if she fails to make a really good impression, there’s not a lot of runway left for her to recover. She hasn’t left a lot of other chances for voters to make their decision.”

Bedford noted that while the newest national polling from the New York Times and Siena College has given Trump a slight boost, the two candidates are tied in Arizona, North Carolina, Georgia, and Nevada.

“She’s said so little about where she stands on the issues,” Bedford also said. “Voters say they really don’t know her, and that’s her biggest vulnerability.”

Bedford added that for Trump to come out of the debate on top, he only needs to “not reinforce the worst perceptions that people have about him.”

“Don’t be a bully, don’t talk over Kamala and get too personal, and if he just clears that pretty low bar, I think he’s in a good position to maintain some of that momentum,” Bedford said.

Tuesday’s debate, hosted by ABC News, will air at 9 p.m. Eastern.
