OKLAHOMA CITY -  Nearly three dozen Oklahoma educators who say they're frustrated by some Republican-backed changes to public education are among those filing for seats in the state House and Senate during the first of a three-day filing period in Oklahoma City.

Candidates for all 101 seats in the Oklahoma House and 25 posts in the 48-member state Senate began filing Wednesday at the state Capitol.

Tulsa teacher and soccer coach John Croisant was among the first to file for state representative Wednesday morning.

Among the other offices on the ballot in November are one U.S. Senate seat, five U.S. House posts, and a six-year term on the Oklahoma Corporation Commission.

Many parents and teachers in Oklahoma say they're growing weary of legislative tinkering with public education. Republican-led attempts this year to approve a voucher system for private schools and consolidate some school districts fueled discontentment among educators.
