The Last Days of Democratic Dominance: 1990 & 1994
In 1990, Oklahoma's political landscape was still shaped by its populist and Democratic roots. While the state had been voting for Republican presidential candidates for decades, state-level politics were a different story. In the 1990 midterm, Democrat David Walters won the governorship, and the immensely popular Democratic U.S. Senator David Boren was reelected in a historic landslide, capturing over 83% of the vote. Democrats controlled the state legislature and most statewide offices, a tradition stretching back to statehood. But the ground was beginning to shift. The 1994 midterm election was a shock to the system. Dubbed the 'Republican Revolution' nationally, its effects were potent in Oklahoma. Republican Frank Keating won the governorship, and for the first
time, the GOP held a majority of statewide elected offices, signaling the beginning of the end of the old Democratic order.
A State in Transition: 1998 & 2002
The late 1990s and early 2000s were a period of political realignment. Governor Frank Keating, a popular Republican, easily won reelection in 1998, further cementing the GOP's growing influence. Yet, Democrats weren't gone. In a stunning 2002 upset, a little-known Democratic state senator named Brad Henry defeated former NFL star and Republican Congressman Steve Largent for the governorship. Henry's victory was razor-thin, aided by a third-party conservative candidate who split the Republican vote and a controversial ballot measure to ban cockfighting, which drove high turnout among rural Democrats. Henry's win proved that a moderate, folksy Democrat could still succeed, but it was an exception that highlighted the broader trend. The state was now a place of split tickets, where voters might elect a Democrat for governor but Republicans for most other offices.
The Red Tide Rises: 2006 & 2010
Governor Brad Henry’s personal popularity led to a landslide reelection in 2006, where he won 66% of the vote against a well-known Republican challenger. But this was the last major statewide victory for the Oklahoma Democratic Party to date. By the 2010 midterms, the transition was complete. Riding a national wave of conservative energy, Republicans didn't just win; they swept every single statewide office in a historic landslide. Mary Fallin became the state's first female governor, and the GOP expanded its legislative majorities to nearly untouchable levels. The 2010 election marked the moment Oklahoma ceased to be a transitional state and became a fully-fledged Republican stronghold, aligning its state-level politics with its national voting patterns.
An Era of Republican Supermajorities: 2014, 2018 & 2022
The midterms of the last decade have only reinforced the GOP's dominance. In 2014, Governor Mary Fallin won reelection, and Republicans continued to hold all statewide offices. The 2018 midterms saw another complete Republican sweep of statewide races, led by newly elected Governor Kevin Stitt. While Democrats made some gains in urban and suburban legislative seats, particularly around Oklahoma City and Tulsa, Republicans consolidated their power in rural Oklahoma, which was once the bedrock of Democratic strength. The 2022 midterms continued the pattern, with Governor Stitt winning reelection and Republicans once again sweeping every statewide contest. The party also holds supermajorities in both chambers of the state legislature, giving them complete control over the state's political agenda.
