The vice president spent most of his speech attacking Republican presidential nominee Mitt Romney and said little about Romney's running mate, U.S. Rep. Paul Ryan of Wisconsin, Politico reported.
Biden reminded supporters of his own "middle-class roots" when he said something about Romney making $20 thousand last year and then corrected it to $20 million.
"The town I lived in didn't make $20 million," Biden, who grew up in Scranton, Pa., said.
About 1,100 enthusiastic supporters greeted Biden, the Beloit News said.
Biden reminded the crowd of the long-term consequences of the election, including Supreme Court appointments.
