The Battle in the Buckeye State

— -- The Whistle Stop train is making its way through Ohio today, a state that could prove to be one of the most crucial swing states this election.

Running a campaign in Ohio is like running in five separate states, each region proving to be its own unique battleground. Watch more about the war being waged in Ohio here.

Regional directors of both campaigns are waging their fights meticulously. The Obama side is counting on numbers, saturating the state with 70 field offices over McCain's 40.

While the McCain side is counting on technology---- using internet phones to help volunteers place more than four thousand calls a night and the time tested tradition of talking to your neighbor.

Experts say the grassroots, phone calls and door knocking might be able to add up to 1 to 2 percent on election day, a percentage that very well could decide a race.
