the nuance of what you noticed. >> it ties into the numbers you just showed. the rational in large part to date has been hillary clinton might be weaken, candidacy might collapse, after the debate performance last week, her poll numbers are up, so it is now imperative for joe booiden to present some real contrast with hillary clinton to make the case to democrats. this is why you should nominate me, this is why i'm different from hillary clinton. also, from biden's standpoint, to anticipate attacks that might come from hillary clinton and o knock late himself against them. we saw a lot of that going on potentially today, this morning, so for example, yesterday, joe biden made comment where he said he doesn't consider republicans his enemy. that was interesting because in the debate last week, hillary clinton bragged that she considers republicans her enemy. she says that's something she takes pride in. biden reiterated those comments this morning, and he also gave something of a shoutout to of all people, dick cheney.
