Presidential geography

By Lester Holt, NBC News anchor

If like me, you don't live in a "battleground state," you may feel like a second-class citizen these days. I say that tongue firmly in cheek, but there's no question that at this point in the campaign, the race for the White House is being fought on a fairly narrow swath of real estate. There are a handful of states which the campaigns believe hold the mathematical keys to attaining the necessary 270 electoral votes. If your state is still solid blue or solid red on political maps, don't expect to see much of either candidate. 

With so little time left, today finds both candidates campaigning in Western states that they believe will seal the deal. Lee Cowan will check in from the Obama campaign in Nevada, and Kelly O'Donnell will catch us up with John McCain's day in New Mexico. Kelly will also shed some light on Sarah Palin's new flash of independence on the trail.
