Moran vs. Tiahrt: In Kansas’ GOP Senate primary today, Reps. Jerry Moran and Todd Tiahrt are battling to succeed Sen. Brownback, who’s running for governor. Both Moran (endorsed by Jim DeMint) and Tiahrt (backed by Sarah Palin) are conservatives, but Moran might a tick or more in the Bennett model (he voted for SCHIP and PAYGO, and Moran’s former campaign manager has accused his former boss of not being “instinctively conservative”). The Moran-Tiahrt winner would be the overwhelming favorite for Brownback’s seat in November. Tiahrt has tried his best to tap into the Tea Party movement and has run the type of primary campaign that has been successful in Nevada and Kentucky, for instance. Most polls in Kansas close at 8:00 pm ET tonight, but a few counties in the western part of the state close at 9:00 pm ET.
