FILE - In this Sept. 9, 2012 file photo, Vice President Joe Biden visits with patrons over lunch at Cruisers Diner in Seaman, Ohio. Biden buddied up with bikers, posed for countless pictures at a pizza place. Obama goes airborne in a doozie of a bear hug with a pizza guy in Florida. Joe Biden cozies up with a biker chick in Ohio. Even the more reserved Mitt Romney seems to be loosening up some with people he meets on the campaign trail. Kissing babies and slapping backs are so yesterday. The 2012 candidates are putting their all into the campaign cliche of pressing the flesh. (AP Photo/Carolyn Kaster, File)
