Republican state Sen. Nick Jordan has dropped out of the GOP primary in retiring Rep. Dennis Moore's (D-Kan.) district.

Jordan's exit leaves state Rep. Kevin Yoder as the only GOP candidate in the race who is raising big money. Yoder will be the favorite the win the GOP nomination in August.

Jordan, the 2008 nominee against Moore, said he worried that a crowded GOP primary would open the door to the likely Democratic nominee, Moore's wife Stephene.

"Yet with so many candidates in the Republican primary for the U.S. House of Representatives, I fear we could provide an opening for our liberal congressman’s liberal wife tco sneak into office in his place," Jordan said.

"With that in mind, Linda and I have decided to end our campaign at this time with deep gratitude for the prayers, support, and encouragement people have so graciously offered the last three years and throughout my public service."
