Two conservative Kansas congressmen swept into office four years ago during a tea party surge face primary races Tuesday from Republican challengers trying to tap into voter dissatisfaction with Washington.
The state's hottest congressional race is in the aircraft manufacturing hub in south-central Kansas' 4th District, where U.S. Rep. Mike Pompeo of Wichita is attempting to fend off a challenge from popular former Congressman Todd Tiahrt.
Tiahrt held the seat for 16 years before giving it up in 2010 for an unsuccessful GOP primary run against U.S. Sen. Jerry Moran.
In the 1st District primary, Clyde farmer and educator Alan LaPolice is challenging U.S. Rep. Tim Huelskamp, trying to capitalize on discontent with the congressman's stances on agricultural issues and recent spats with party leaders.
The marquee race of the day involves incumbent Sen. Pat Roberts facing off against tea party challenger Milton Wolf.
There are statewide office primaries for governor, insurance commissioner and secretary of state.
