Mr. Obama, like last year, will celebrate Independence Day with military families he's invited to the White House for a barbeque, concert and a chance to view fireworks from 1600 Pennsylvania Ave. Romney, meanwhile, will participate in a parade with his family in Wolfeboro, N.H. The former Massachusetts governor has an estate in Wolfeboro where the Romney family is vacationing this week. Not all presidential candidates spend the Fourth celebrating; for some candidates in years past, Independence Day was a day like any other to win votes. Some candidates, meanwhile, mixed patriotism with politics. Here's a look at some past Fourth of July campaigns.
