2. Georgia Senate (May 20)

The Georgia GOP primary is a race that national Democrats watch with glee. It’s a free-for-all with eight declared candidates thus far, including U.S. Reps. Paul Broun, Phil Gingrey and Jack Kingston, businessman David Perdue and former Georgia Secretary of State Karen Handel.

It’s also one of the places Democrats say is most likely to produce 2014’s Todd Akin “legitimate rape” moment, given the propensity of certain candidates in the race to say less-than-politically-correct things (Gingrey, for example, endorsed traditional gender roles).

Whoever wins the primary will take on nonprofit CEO Michelle Nunn, daughter of longtime Georgia pol Sam Nunn, in the general election. The crazier this primary gets, the more hopeful national Democrats will be that Nunn can make a typically red seat competitive for them.
