But I think the thing is, when he said the wrong words and stumbled historically when we both covered him before, it's Uncle Joe. It's, like, OK, it's Joe Biden, he's great, look, whatever. Much like in some ways the awkward touching and that kind of thing.

But when you are the frontrunner for — to be president and everyone thinks you may actually have a shot at getting the Democratic nomination, everyone is going to pay even more attention to every little stumble, and I do think that is going to get worse. Now, some of why this has been highlighted is Trump's team is the one who sort of pushed this narrative event. I am interested to see if like a lower tier presidential candidate goes along this narrative, like a one who's actually on the Democratic side, because, of course, President Trump is going to push this. He wants to beat Biden. He thinks Biden is the guy to beat.

But does — do the Cory Bookers of the world or does someone else start trying to talk about Joe Biden's age and play these gaffes or anything like that, does it cause Democratic infighting? And I think that's something to be more worried more about at this stage with Biden.
