Another day in this crucial swing state, another visit from somebody on a presidential ticket.

The Republican vice presidential hopeful was in Virginia just days ago, campaigning in Glen Allen and Springfield on Friday. The previous Saturday, presumptive Republican presidential nominee Mitt Romney unveiled his running mate in Norfolk.

In between, Vice President Biden made a memorable trip to Danville, where he attracted lots of attention by telling the crowd that Romney’s approach to regulating the financial industry would “put y’all back in chains.”

Romney, President Obama and their high-profile surrogates have made multiple visits to the key swing state, where Obama leads Romney 51 percent to 44 percent among registered voters, according to a Washington Post poll.
