OKLAHOMA CITY Voters in central Oklahoma on Tuesday will pare down a crowded field of congressional hopefuls seeking to represent the 5th District in Washington. Nine Republicans are vying for the seat held by first-term U.S. Rep. Kendra Horn, the only Democrat in the states delegation. Four of the GOP challengers have raised more than $500,000, including businesswoman Terry Neese, state Sen. Stephanie Bice, former State Superintendent Janet Barresi and businessman David Hill. Republican U.S. Sen. Jim Inhofe and U.S. Reps. Markwayne Mullin and Tom Cole all are heavy favorites in their GOP primaries Tuesday. Inhofe faces three lesser-known candidates in the GOP primary, while four Democrats are running for the opportunity to challenge him in the fall.
