State Sen. Carolyn McGinn, R-Sedgwick, decided not to run and endorsed Mike Pompeo, president of Sentry International, an oilfield and industrial machinery company, and a Republican national committeeman.

McGinn said she plans to focus on projects on her family’s farm and on local issues.

Pompeo and State Sen. Dick Kelsey, R-Goddard, are the only Republican candidates to file for the seat thus far.

Kelsey recently drew an endorsement from former Kansas republican gubernatorial candidate Dr. Ken Canfield.

Other names that have been floated for the Republican side of the race include state Rep. Steve Brunk, R-Bel Aire; state Sen. Susan Wagle, R-Wichita; state Senate Majority Leader Derek Schmidt, R-Independence; and Wichita businessman and entrepreneur Wink Hartman.
