Final unofficial tallies from the November 3 general election in Oklahoma’s 1st Congressional District show Republican nominee Mark Tedford defeating Democrat John Croisant by roughly 4.6 points, aligning with the 0-5% Republican margin band. The open seat, vacated by Kevin Hern to pursue a Senate bid, produced a tighter contest than the district’s prior double-digit Republican margins after a crowded GOP primary that Tedford won and a Democratic campaign that narrowed the partisan gap in Tulsa County. With over 99% of precincts reporting and consistent updates across sources, trader consensus prices the narrow outcome at 99.2% amid minimal remaining uncertainty over certification or provisional ballots. Late shifts in the final canvass or successful legal challenges could still move the result outside this band.
