Complete, but unofficial, returns showed Gibbs with 28 percent of the vote in House District 36 followed by Eddie Longstreet and Jeannie Johnson Staten (STAY'-tuhn), who each got 22 percent. Results showed Longstreet with five votes more than Staten.
If the results stand, Longstreet will be in the runoff with Gibbs.
Six candidates were on Tuesday's ballot.
House District 36 encompasses parts of Clay, Lowndes and Monroe counties. The seat was left vacant by the Jan. 13 death of Democratic Rep. David Gibbs, who had served since 1993.
The winner will serve through the current four-year term, which ends in January of 2016.
