Loving this so far, though I question why you left Brownback as unopposed in Kansas. He seems relatively vulnerable based on recent polling, so I'm sure that some Democrats would pounce at that opportunity.
Good call. I did it because I couldn't think of a plausible candidate (with Brewer running for Senate, and Sebelius staying in Obama's cabinet until 2017), but I just figured someone out.
If anything I'd switch Roberts out. He's susceptible to a primary challenge, but he's even having trouble fielding a primary candidate. Brownback is more susceptible than Roberts for a Brewer challenge.
