A Democratic school teacher has defeated a Republican businessman in a special election for a House seat in west Norman, making it the third Republican-held seat Democrats have captured in special elections this year.

According to unofficial election results Tuesday, Democrat Jacob Rosecrants collected 60 percent of the vote to defeat Republican Darin Chambers in the race for House District 46, where Republicans had a nearly 3,000 voter-registration advantage. The two were vying to replace former GOP state Rep. Scott Martin, who resigned in May to take a position as director of the Norman Chamber of Commerce.

And in Tulsa's Senate District 37, Republican voters selected Brian O'Hara in a winner-take-all primary to replace outgoing Republican state Sen. Dan Newberry. O'Hara, who attracted nearly 42 percent of the vote in a seven-person GOP field, will face Democrat Allison Ikley-Freeman on Nov. 14.
