Crossroads blitzing 5 Senate races

Apparently, the GOP independent-spending behemoth American Crossroads will launch a new wave of Senate ads totaling over $7 million in TV time.

The ads start August 8 and will run through Aug. 21, targeting Missouri, Montana, Nevada, North Dakota and Virginia. The price tag is about $7.2 million. Those five states are at the top of the GOP's takeover list for the 2012 cycle, and Republicans will have to win most of them to take control of the Senate.
