While turnout increased statewide, Democratic counties with large populations saw among the biggest gains on Election Day.
Turnout statewide in 2018 was 55 percent, compared to 40.35 percent in 2014 and 52.71% in 2010. In 2018, 693,893 voters cast ballots*, the most of any midterm in state history.
This is the easy way to explain how Democratic gubernatorial candidate Michelle Lujan Grisham won by a large margin, and also why Democrats all the way down the ballot had a successful night.
Digging further down into the numbers, it shows just how impressive turnout was in some districts, while in others turnout lagged. It isn’t difficult to pick out the pattern when exploring it at the county level.
In Lujan Grisham’s home of Bernalillo County, 56.84 of registered voters cast ballots, topping any midterm election since 2000.
Just over two-thirds of Santa Fe County’s registered voters turned out, which is a new record for the last two decades. The Democratic stronghold previously failed to even hit 60 percent in any midterm since 2000. And Doña Ana County cracked 50 percent turnout (51.73 percent) for the first midterm in the same time period.
These three counties alone, all of which were dominated by Democrats, made up over 52 percent of the vote this year.
And, like this year, in 2010, the big three Democratic counties made up more than half of the vote.
In all, 86,193 more voters cast ballots in 2018 than 2010. Even when factoring in an increase in registered voters, turnout increased by 2.29 percent.
The counties that saw an increase in turnout of at least one percentage point between 2010 and 2018 were nearly all counties Lujan Grisham and other Democrats won.
- Santa Fe: 7.48 percentage point increase
- San Miguel: 6.6 percentage point increase
- Taos: 6.57 percentage point increase
- Bernalillo: 5.27 percentage point increase
- Doña Ana: 4 percentage point increase
- Los Alamos: 3.96 percentage point increase
- Cibola: 2.78 percentage point increase
- Sandoval: 2.4 percentage point increase
- Sierra: 1.56 percentage point increase
- Grant: 1.47 percentage point increase
Of these, only Sierra County saw such an increase while voting for primarily Republicans. (Attorney General Hector Balderas did carry the county)
Meanwhile, the biggest drop came in Lea County, a key Republican county in southeast New Mexico—and Pearce’s home county. Not only did the turnout drop by 7.26 percentage points, but 861 fewer voters turned out in 2018 than 2010.
Chaves, Otero, and Eddy, along with Lea, are all important Republican counties in southern New Mexico. All had lower turnout rates in 2018 compared to 2010. San Juan, the fifth-most-populous county in the state and also a Republican stronghold, also saw a decline in turnout.
The turnout was much higher when compared to 2014—which had record-low turnout—in nearly every county.
Turnout in 2002 and 2006 was largely in the same range as 2010 (52.98 percent and 52.21 percent).
Los Alamos County once again had the highest turnout int he state, hitting 72.3 percent.
But thanks to a higher amount of registered voters and the higher turnout, 2018 will be a number hard for future midterms to break.
Still, there is still room for improvement: In 1994, when Gary Johnson defeated Bruce King, 68 percent of registered voters went to the polls, in line with the 65 percent from 1990.

Correction: This story originally said Sierra County was among those where statewide Democrats won. Only AG Hector Balderas did.
Update: Added the statewide turnout numbers from 2010, 2014 and 2018.
