Swing state spending

The Obama campaign is substantially outspending McCain and the RNC on TV in the battlegrounds. ($1.5 million in NC?)

We know that Obama has a larger ground operation, so, where is McCain's money going or gone? Are they hoarding it? Is it spent? Or is the Obama fundraising advantage that severe?

(Would love to see the Obama campaign's Sept. numbers.)

Later: The UAW dumps $3 million on TV in Mich, Oh, In, Pa.

Also: Some big voter registration numbers in Pa, Fla, and Oh.
