TULSA, Okla. (AP) _ State Rep. John Sullivan easily outpaced Oklahoma first lady Cathy Keating in the race to succeed U.S. Rep. Steve Largent, but she received enough of the vote to force a runoff election next month.

Former Tulsa school board member Doug Dodd won the Democratic primary. Largent is resigning to run for governor.

Final unofficial vote totals showed Sullivan had 46 percent, or 19,018 votes, and Keating, wife of Gov. Frank Keating, had 30 percent, or 12,736 votes. Since Sullivan failed to get more than 50 percent of the vote, he will have to face Keating in a runoff on Jan. 8. The general election will be held on Feb. 12.

On the Democratic side, Dodd had 12,516 votes, or 89 percent, to 1,584 votes or 11 percent for James Lamkin.

The 1st Congressional District seat held by Largent includes all of Tulsa County and part of Wagoner County. The general election is Feb. 12.

Largent, a former football star, is resigning Feb. 15 in his bid to succeed Keating, who is completing his second and final term.
