OKLAHOMA CITY (AP) Longtime state and federal prosecutor Rob Wallace has defeated Muskogee seed seller Wayne Herriman for the Democratic Party nomination in Oklahoma's 2nd Congressional District.

Wallace will try to keep the seat in Democratic hands this fall against a Republican nominee also selected Tuesday. Congressman Dan Boren announced last year he wouldn't seek re-election.

The 49-year-old Wallace of Fort Gibson enjoyed endorsements from some of the state's most popular Democrats, including former Gov. Brad Henry, former Attorney General Drew Edmondson and University of Oklahoma President David Boren, the incumbent's father.

Wallace touted himself as a Democrat who fits the increasingly conservative 2nd District.

Wallace will join the GOP candidate and independent Michael Fulks on the November ballot.

Dan Boren is currently Oklahoma's only Democratic congressman.
