Analysis
As he had managed in other primarily white Great Plains states including neighboring Kansas, Bernie Sanders won a convincing ten-point victory in Oklahoma. This marked a clear difference from 2008 when Hillary Clinton had won the state by 21 points against Barack Obama, winning 76 of the state's 77 counties. According to exit polls, Sanders won men 60-33, younger voters 76-23, white voters 56-36, and Independent voters 69-21. Clinton, for her part, won women 48-46, older voters 50-41, non-white voters 56-40, and Democrats 52-43. A majority of voters in the primary said they thought Clinton was not honest or trustworthy, 51-47.

Sanders swept 75 of Oklahoma's 77 counties. He performed strongly in the major cities of Norman, Stillwater, Enid, and Moore. He narrowly edged out Clinton in Tulsa County by a margin of 2.28%. Clinton narrowly won in Oklahoma County (the only county to vote for Obama in the 2008 primary), home to Oklahoma City, and Osage County, home of the Osage Native American tribe.

Sanders won most of the rural, majority white and deeply conservative counties of the state, including those in the Oklahoma Panhandle, Little Dixie, and Southwestern Oklahoma which are among the most radically conservative areas of the nation. The Little Dixie region in particular was the base of President Bill Clinton's support in the 1992 and 1996 elections, as this area consists of socially conservative but economically liberal Democrats, many of whom were drawn to Sanders's opposition to trade deals like NAFTA.
