Voter Registration Maps: Oklahoma gets redder with Trump

Here's the 2025 installment of my long-running Voter Registration Maps series. My last update came in May, after Coal County became the 77th and final county to have a Republican plurality. After a brief setback in 2023 (first decline in 26 years), registration changes once again benefited the GOP in 2024 - riding the Trump coattails, no doubt.

From January 2023 to March 2024, Coal County was the lone county with a Democratic voter registration lead. For the foreseeable future, that era now belongs to the history books. It may well be many years before Democrats re-take the lead in any county, if they're able to at all.

The above map shows the leading political party by county, whether holding a plurality or an outright majority of registered voters. The blue color that once dominated the state has now completely disappeared on a county-level. The GOP has plurality leads in 7 counties (with 4 of them being less than 2.5% from majority status), and outright majorities in the remaining 70 counties.

Overall trends went to the GOP in all but Canadian, Garfield, and Texas counties, which leaned slightly in favor of Independents (Democrats rank third in those counties). Larger swings in southeast and southwest Oklahoma helped push four GOP-plurality counties over the majority mark.

Republicans grew as a percentage of county registered voters in all but Canadian, Oklahoma, Tulsa, and Texas counties, but even those declines were small (between 0.13% and 0.37%) and came from competition with Independent voters, not Democratic.

Democrats have not increased percentages in any county since 2013, and the trend shows no signs of letting up. After decades of ground lost to Republicans, they are now increasingly losing to Independents (as shown in the final two graphics).

Independents grew in 68 of 77 counties. Of note, Independent voter growth outpaced the GOP in Canadian County by 1.36%, Cleveland by 0.78%, Comanche by 0.14%, Garfield by 0.79%, Greer by 0.08%, Jackson by 1.08%, Logan by 0.44%, Noble by 0.05%, Oklahoma by 1.26%, Payne by 0.52%, Rogers by 0.04%, Texas by 1.4%, and Tulsa by 1.23%. By contrast, there wasn't a single county where Independents lost ground to Democrats. 

Independents lead Democrats in seven counties across the state: Beaver (+1.94%), Canadian (+0.7%), Garfield (+2.43%), Major (+2.02%), Texas (+3.8%), Washington (+1.91%), and Woodward (+2.46%). They are on the verge of eclipsing Democrats in Alfalfa (-0.52%), Jackson (-0.29%), Kay (-0.43%), Logan (-0.08%), and McClain (-0.6%), as well as 23 other counties where they trail Democrats by between 1% and 5%.
