'You know, the idea here that somehow these guys are, once again, injecting fear and loathing into this campaign I think is mildly dangerous,' Biden added.'I mean, here you have out there these kinds of, you know, incitements out there — a guy introducing Barack using his middle name as if it's some epitaph or something. This is over the top.'

On ABC’s 'Good Morning America' the Democratic vice presidential candidate said that since Palin announced that the 'heels are on, the gloves are off' she has crossed the line at her rallies and is encouraging supporters who Biden believes are going 'overboard.'

'I think it goes way too far,' Biden said. 'Look, this really is a case where when you don't have anything to talk about, attack. And it gets really over the edge.'

'I mean, some of the stuff she's saying about Barack Obama and the stuff that people are yelling from the crowd, if she hears it, she should be at least saying, whoa, whoa, whoa; that's overboard. I mean, you know, this is — this is volatile stuff. And it's — I just — I felt we were kind of beyond this place that it seems to be going.'
