Though Rep. Todd Tiahrt, R-Goddard, has filled the 4th Congressional District seat for 14 years, not every Kansan sees it as a given for the GOP when Tiahrt gives it up in 2010. "This district is not necessarily a win for the Republicans," Joe Aistrup, political science professor and interim dean of arts and sciences at Kansas State University, told CQPolitics. "Wichita has a history of supporting Democrats over the course of time. The district used to be Democratic-leaning, and now it is Republican-leaning. There are some Democrats that could make a go for the seat." So far, retired court services officer Robert Tillman is the only Democrat to file for it; declared Republicans are state Sen. Dick Kelsey and businessman Michael Pompeo.
