And though Obama's unpopularity in rural Oklahoma may have hindered Democrat Rob Wallace's bid to replace Boren, the president actually outperformed Wallace in three counties, including Cherokee County, where the Cherokee Nation is based.
Obama got 6,137 votes in Cherokee County, while Wallace got 6,021.
Mullin is a Cherokee. Cherokee Nation Chief Bill John Baker is a vocal supporter of Obama.
Oklahoma native holds Kennedy's Senate seat
By now, most people who followed the U.S. Senate race in Massachusetts know that Democrat Elizabeth Warren is not an enrolled Cherokee.
But when she takes office in office in January, she will have this distinction: She'll be the only member of the U.S. Senate who was born in Oklahoma.
Neither of Oklahoma's senators was born in the state. Sen. Tom Coburn was born in Wyoming, and Sen. Jim Inhofe was born in Iowa. A check on the biographies of current and incoming senators found no others born in Oklahoma.
Warren, 63, was born and raised in Oklahoma City, and graduated from Northwest Classen High School.
The former Harvard professor has not lived in the state in decades but still visits family regularly.
Oklahomans chipped in $30,600 to her campaign (which raised more than $39 million). She got money from doctors, lawyers, business people and Oklahoma Bankers Association President Roger Beverage, who wound up a supporter despite once calling her the “anti-Christ” while she was setting up a consumer advocacy agency in Washington.
Warren will take over the Senate seat that long belonged to the late Ted Kennedy.
