Kansas is traditionally one of the most Republican states in the nation and I would expect that to remain the same, though there is a chance that could change.
President: No Democrat as come even close to carrying Kansas in 40 years and unless Obama picks Governor Sebelius that is unlikely to change. Even with her on the ticket the GOP would have a slight edge.
Safe Republican
Senate: The GOP is even stronger when it comes to Senate races in Kansas. In fact the last time a Democrat won a Senate race in Kansas neither Presidential candidate was alive. Incumbent Pat Roberts will easily defeat his Democratic opponent Lee Jones.
Safe Republican
House: Republicans will hold on to the 1st and 4th District with ease. The GOP will target both Democratic seats but incumbent Dennis Moore should hold on.
In the 2nd District we have incumbent Nancy Boyda against former Congressman Jim Ryun. Boyda was one of the major upset winners in 2006 and will be hard pressed to hold her seat against a McCain/Roberts tide. Given the GOP nature of the district it looks to be a pickup.
Leans Republican
With this gain for the Republicans the Democrats are now +2 in the House
