This is what he says,
"Not because I'm running, but because who I'm running against, this is the most consequential election in a long, long, long time," Biden said. "And the character of the country in my view is literally on the ballot. What kind of country we're gonna be? Four more years of George, ah, George... gonna find ourselves in a position where if Trump gets elected we're going to be in a different world."
Four more years of George, then he stumbles, ah, says George, again. He got them all mixed up, George Bush, George the interviewer and Trump (who I'm running against). It is all right there in how he said this. VERY SAD!
It also fits in with all his other gaffes. Totally not out of character for Biden.
