A handful of other states remain up for grabs, with Florida offering the biggest payoff -- 29 electoral votes. Other battlegrounds include Virginia, Colorado, Nevada, Wisconsin and New Hampshire. To understand how important Ohio is, look at the number of times the candidates appear in the state. According to the campaigns, Romney has been to Ohio 22 times this year for 60 events, while Obama has visited 18 times to hold 23 political events and another six events for official business. Compare that to Florida: Romney visited 17 times this year for 58 events; Obama 13 times for 25 political events plus seven official events.
