Campaigns invade other sides' turf
MASON, Ohio - Some campaign workers in the battleground state of Ohio have a particularly challenging mission: find votes in opposition territory.
President Barack Obama's campaign did well with that strategy in 2008, and won Ohio. The campaign has expanded such behind-the-lines efforts this year in places such as the three conservative counties around Cincinnati.
They're not looking to win the counties, but rather to bite into the 2-to-1 margins to pick up thousands of additional votes. With Ohio appearing close and pivotal, even small pockets of votes could be decisive.
Republican rival Mitt Romney's campaign has gone into traditionally Democratic counties in the northeastern part of the state for the same reason.
Both sides also are looking for votes on the other's turf in swing states such as Colorado and Florida.
