On the final weekend of their deadlocked campaign, President Barack Obama and Mitt Romney called forth every supporter they could muster to gain any possible edge they could find.

In a tiny New Hampshire town, four out-of-state surrogates for Romney chatted with the lunchtime crowd at a diner decorated with a pink Cadillac on stilts. In Reno, Nev., an Olympic speedskater talked up the Republican nominee. In Virginia, Sens. John McCain of Arizona and Lindsey Graham of South Carolina targeted voters in military communities. Two of Romney's sons campaigned door-to-door in Florida.

Not to be outdone, the Obama campaign sent out its stars on Saturday. Katy Perry, decked out in a body-hugging blue leather dress with the Obama campaign slogan "Forward" on it, rocked the stage before Obama's speech in Milwaukee. John Mellencamp did an acoustic rendition of "Small Town" in Dubuque, Iowa. Dave Matthews was scheduled to perform ahead of Obama's appearance Saturday night in Northern Virginia.
