Phillip Martin appears to have a solid lock on a seventh consecutive, four-year term as tribal chief of the Mississippi Band of Choctaw Indians.
Unofficial returns give Martin a commanding 64 percent lead over opponents Bobby Thompson, Linda Farve and Kennith H. York.
Choctaw officials said final, official returns should be available by Friday.
Tribe spokeswoman Creda Stewart said she anticipates that returns will show a record number of voters in this election, which also included races for eight of 16 tribal council seats. Those numbers were not available Wednesday.
Since Martin was first elected in 1979, the tribe has opened more than two dozen businesses. The largest is the $600 million Pearl River Resort, which includes two hotel-casinos, a water park, lake, Hard Rock Beach Club and white sands beach.
The 9100 member tribe has a 35,000 acre reservation sprawling across ten counties, with the majority of the land in Neshoba County.
