Every top Republican official in Kansas threw their support behind Sen. Pat Roberts’ re-election campaign on Thursday, signaling that the three-term senator is unlikely to get a primary challenge in 2014.

Roberts released a list of endorsements that included Gov. Sam Brownback, Secretary of State Kris Kobach, National Republican Senatorial Committee Chairman Jerry Moran of Kansas, every House member in the congressional delegation and many others.

The Sunflower State is safe GOP territory, and Republicans are expected to hold the seat in 2014. But earlier this cycle, some quietly wondered if Roberts would face a primary challenge.

Kobach was the most-often mentioned possible challenger, CQ Roll Call noted in November. Now it’s clear the secretary of State is throwing his support behind Roberts, along with many others.

“No one fights for Kansas and Kansans harder or more effectively than Pat Roberts,” Moran said in a release. “I am honored to be on Pat’s team and look forward to continuing our work together to put Kansas first.”
