WICHITA, Kan. (AP) — The chairman of the National Republican Senatorial Committee says as hard as the GOP is working to win Republican control of the U.S. Senate, Kansas can’t be the place that fails the party.

Sen. Jerry Moran of Kansas told business leaders Friday in Wichita that as hard as Republicans are working to win seats across the country, it would be a “terrible mistake” for Kansas to fail to keep Pat Roberts in the Senate.

Moran also urged his audience to imagine the circumstance where the GOP puts in so much effort and Republican Gov. Sam Brownback is not re-elected.

Both Brownback and Roberts are facing tough re-election battles.
