>> yeah. i was talking to one of the campaigns today about this very issue. and you know, i think one of the things you're seeing with some of these civil rights leaders coming to biden's defense, there is not much of an appetite among democrats to really go after each other. we had a nasty primary in the 2016 cycle, and they don't want to have sort of that knockdown dragout fight again. many of them are genuine friends. at the same time, we've already seen with cory booker and kamala harris condemning the comments, they're going to go after specific differences that they see with these candidates. so i don't think you're going to see a real sort of shark pile on attack on biden on that debate stage. i think there's a fear that that might really backfire. at the same time, these candidates are going to have to draw distinctions between themselves. and when they see an opportunity to go after sort of an idea instead of a person which is something cory booker talked about.
