Incumbent Rep. Kevin Hern's March Senate bid opened Oklahoma's 1st Congressional District, a Solid Republican seat with R+11 partisan voting index, driving trader consensus to 87% odds for a GOP hold. The June 16 Republican primary pits over 10 candidates, including fundraising leader state Rep. Mark Tedford ($696K cash on hand) and Corporation Commission Chair Kim David, against unopposed Democrat John Croisant, a former teacher and Tulsa school board member with $36K cash. Lt. Col. Dan Rooney's withdrawal this week, citing President Trump's endorsement of a rival, streamlines the GOP field ahead of the primary and potential August runoff, underscoring minimal Democratic path in this reliably red battleground. General election looms November 3.
