A tipster sent us over this recently prepared research that outlines the media buys for the Georgia Senate candidates. The screaming headline is that more than $5 million has already been spent by the candidates and outside forces ahead of the May 20 primary.

Look a little closer, though, and you'll find some other interesting tidbits. One is that Ending Spending, the conservative Super PAC going after Democrat Michelle Nunn is spending a lot more than the $150,000 initially reported. Ending Spending confirmed the $1.3 million buy and said it will pay for more than just that one anti-Nunn ad, but the group would not provide further details.

The numbers represent media buys for ads the campaigns have already run or reserved for the future. Not surprisingly, Rep. Jack Kingston and businessman David Perdue, who have some of the biggest hauls, also have the biggest buys. And Democrat Michelle Nunn, facing little-known challengers in her party's primary, seems to be conserving her campaign cash with the exception of a few strategic TV buys.

Rep. Phil Gingrey is focusing his ad spending on his home base of Atlanta with an ad buy of $725,000 in the metro market, while Kingston and Perdue are spreading their buys around the state.

Rep. Paul Broun and former Georgia Secretary of State Karen Handel, who trail the others in fundraising, also have the fewest media buys. (Handel's campaign disputes the figure you see above, but concedes it doesn't yet have the fiscal firepower to match her rivals).
