MAPS: Oklahoma voter registration changes, 2025 to 2026

Here's the 2026 installment of my long-running Voter Registration Maps series. As you can see, there is no blue on the map; the Republican Party has held leads in all 77 counties since March of 2024, the culmination of a decades-long trend, when Coal County became the final one to flip.

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 outright majorities in 70 out of 77 counties. The counties where Republicans have plurality leads are as follows: Cherokee (45.83% registered voters), Cleveland (47.73%), Comanche (44.35%), Muskogee, (49.39%), Oklahoma (41.39%), and Tulsa (48.07%). Coal County, the last Democratic-plurality county that flipped in 2024? It's now a majority Republican county, 51.96% to 34.08% (incredible).

Overall trends went to the GOP in all but Beaver, Canadian, Major, and Texas counties, which leaned slightly in favor of Independents (Democrats rank third in those counties). 

We'll examine the movement by party in each county in a later post.
