Both tickets are campaigning as duos today after weeks of dividing up the map. President Obama and Vice President Biden will appear together at a rally in Dayton, Ohio; Mitt Romney and Rep. Paul Ryan will rally together in Henderson, Nevada and Morrison, Colo.

The rallies kick off the final, most intense stage of the presidential campaign. Both candidates will criss-cross the map over the next two weeks, trying to cover as much ground as possible. 

After today's rally, Obama will split off for a six-state battleground blitz, sleeping on Air Force One as he travels through Iowa, Colorado, Nevada, Florida, Virginia and Ohio. Romney will make another stop in Nevada before heading to Iowa and then Ohio. He's  planning to hit two or three states a day, or that many events in a large state.
