 voters are going to react on this election about Donald Trump and about Joe Biden. And to the extent that a vice president or vice presidential nominee is really relevant here, I think that goes to those voters who are asking themselves, is Joe up to the job and what their comfort level may or may not be on Kamala Harris. Vance will raise money, will give speeches and things like that, but has a real impact on the race. It's hard to see much of one.
