Why is McCain going to Tennessee?

CNN lists John McCain's stops tomorrow, the final day of the campaign before the election.

Although most of the states are the ones you would expect, the key battleground states, one sprang out at me: Tennessee.

I don't understand why McCain is campaigning there in the last 48 hours. According to Electoral Vote, McCain is 14 points ahead there and Obama has never even been close. Given that Tennessee is a neighbouring state to Georgia (McCain ahead by four points) and Missouri (McCain ahead by one point), this seems a bizarre choice. It's not even as if it's a close contest in the Senate election, with Republican Lamar Alexander up by 61-36 against his Democratic opponent.

Can anyone think of a convincing reason as to why McCain is bothering with Tennessee at this late stage in the campaign?

UPDATE: I saw this just after I posted the above and apparently McCain's trying to get media coverage in south-west Virginia. But the article does highlight just how desperate McCain is in the closing stages of the campaign.
