Crossroads up with new ads in Virginia, Ohio and Nevada

The football-themed Ohio ad mocks Sen. Sherrod Brown (D-Ohio) for voting with President Obama, while the Nevada ad accuses Rep. Shelley Berkley (D-Nev.) of lying in her own Medicare-themed attack ads against Sen. Dean Heller (R-Nev.), then accuses her of voting to cut the program because she supported Democrats' health insurance overhaul law.
