I hate to inform you, but that wasn't a "giant bunny" – it was a person in a rabbit costume
. Biden was just going along with the spirit of the event, as politicians are often compelled to do in those situations. I admit, it would be nice to see someone in campaign mode eschew such stupidity but I'm not holding my breath. As far as shaking hands "with people who are not there", that clip was taken out of context. He had people gathered on stage on either side of him and he turned to address them after he'd completed his speech.
What I really want to say is, I resent having to defend Biden against these types of small minded attacks when there are such great issues to be considered.
I agree completely and couldn't have said it better myself.
