John Croisant, a member of the Tulsa school board, is the Democratic nominee for Oklahoma's 1st congressional district, which is based in the Tulsa metropolitan area. The seat is open because Republican incumbent Kevin Hern announced on March 11, 2026, that he would run for the U.S. Senate.
Croisant became the nominee after nonprofit director Erica Watkins withdrew from the Democratic race to run for the Oklahoma State Senate.
In the general election on November 3, 2026, he faces Republican Mark Tedford, a state representative from the 69th district who won his party's nomination after Jackson Lahmeyer withdrew from their runoff.
