“I have a simple proposition here. I’m here to ask you for your help. Where I come from you don’t get far unless you ask,” said Biden.

“My name is Joe Biden. I’m a Democratic candidate for the United States Senate. Look me over. [slurs words]..if you don’t like me, you can vote for the other Biden — give me a look though, okay?”
