Businessman and Republican National Committee member Mike Pompeo survived a five-way primary in the race for the congressional seat being left open by Rep. Todd Tiahrt (R-Kan.).

The AP called the race for Pompeo with 86 percent of precincts reporting. Pompeo had 39 percent of the vote to state Sen. Jean Schodorf's 24 percent and businessman Wink Hartman's 23 percent. 

Pompeo and Hartman were the early favorites given their strong fundraising numbers. But the two have been attacking one another for weeks, both in the press and on the airwaves.

Heading into Tuesday, the constant sparring between the two frontrunners appeared to leave an opening for Schodorf, who trailed Pompeo by just seven points in the last Survey USA poll of the race.

While Schodorf, a pro-choice Republican, ultimately fell well short of Pompeo, she did finish a surprise second ahead of Hartman.

On the Democratic side, state Rep. Raj Goyle won his primary in a landslide. Goyle, who held a commanding lead in both fundraising and in the polls ahead of the primary defeated Democrat Robert Tillman 80 percent to 20 percent.

Goyle raised more than $1.2 million for his race, while Tillman failed to report any fundraising to the Federal Election Commission.
