A look at Johnson County’s voting history reveals shifting party loyalties, changing demographics, and the importance of individual candidates.
The blue wave we’ve been hearing about for the past year broke far from Tennessee’s shores. However you feel about the outcome, we can all be happy the midterms are behind us. No more obnoxious commercials interrupting football, cringey fundraising texts, or huge campaign signs blocking intersections. Johnson County voted much as it usually does, and Tennessee did as well.
But it wouldn’t be an election year without some post-election analysis, and when you combine that with a data dive, I can’t resist. So here is The Johnson County Line’s autopsy of Johnson County voting patterns.
Midterm elections traditionally attract fewer voters than presidential elections, but they help establish each party’s base of engaged voters. We’ve included presidential results to track longer-term patterns. First, though, a quick look at population.
Johnson County’s population hovered around 18,000 before 2020. Between July 2020 and July 2025, deaths exceeded births by approximately 721, but positive net migration more than offset that decline. The population increased by 4%, approaching 19,000.
Historically a Republican stronghold, Johnson County nevertheless gave Democrats a fairly steady share of the vote until recently. Democratic presidential votes remained near 1,800 from 2000–2008, peaking with Barack Obama, although their share fell from about 33% to 28% of the two-party vote. In 2012, Democratic votes dropped to 1,400, then below 1,000 in 2016, before recovering to around 1,200 in 2020 and 2024.
Republican presidential votes, meanwhile, held around 4,500 before jumping to 5,400 in 2016 and climbing to 6,800 in 2024.
Using midterm results to estimate each party’s engaged base, Johnson County Democrats have fallen from over 1,000 votes to around 600, while Republicans have grown from 3,400 to over 4,400. Democrats may therefore depend increasingly on independents and swing voters, but apart from 2020’s down-ballot races, their candidates have struggled to attract them.
Statewide, the picture differs. Tennessee Democrats are attracting roughly 200,000–300,000 more votes than a decade ago. Republicans still comfortably outpace them, having added around 400,000 votes to their base.
The lazy explanation sometimes blames race or gender, but the data doesn’t support that claim. Barack Obama, the first Black president, received more Johnson County votes than any other Democratic presidential candidate in our survey. Hillary Clinton was historically unpopular, but Kamala Harris, the first woman of color nominated for president by a major party, performed almost identically to Joe Biden.
Down-ballot results tell a similar story. Republican gubernatorial candidates have gained support while Democrats have lost ground. But Senate races suggest candidate quality matters. Popular former Governor Phil Bredesen received more Johnson County votes than any other Democratic Senate candidate in our survey. Marquita Bradshaw, the first Black woman nominated for the U.S. Senate by a major Tennessee party, outperformed most of the white male Democratic candidates who preceded her.
Interestingly, 2020 was a good year for Johnson County Democrats. Blair Walsingham, running against Diana Harshbarger, received 1,214 votes, nearly 58% above the 769-vote average for Democratic House candidates between 2008 and 2016. Democrats have frequently failed to field candidates for state legislative seats, complicating comparisons. Nevertheless, Amber Riddle’s 2020 state Senate performance exceeded that of most previous Democratic candidates, as did Lori Love’s 2024 state House showing.
Nationally, the parties’ bases were also shifting. White voters without college degrees represented 59% of the Democratic base in 1996, but only 26% by 2023. Not all those voters became Republicans, but the shift accompanies a changing perception of Democrats as culturally distant, overly ideological, and insufficiently attentive to working-class concerns.
That perception may influence how Johnson County voters respond to candidates. Those who appeal to working-class voters, like Bredesen and Walsingham, appear to attract more swing and independent support than “resistance” candidates like Gloria Johnson, best known as a member of the Tennessee Three, two of whom were expelled from the legislature following a gun-control protest on the House floor.
Campaign strategy matters, too. In 2020, Walsingham and Riddle visited Johnson County repeatedly, meeting voters at events like the Sunflower and Cranberry festivals. Lori Love regularly attends local events as well. Candidates like Burke, Johnson, or Greene, whose visits are typically one-time and semi-private, tend to fare less well.
Despite a Republican clean sweep, the blue wave that crashed into a number of red states may have trickled into Johnson County and Tennessee. Jerri Greene, who ran for governor this year on more kitchen-table issues, outperformed other candidates going back to 2018 in Johnson County and did even better statewide. Bucking the trend slightly, Kristi Burke, the Democrat running to represent our district in the U.S. House of Representatives, may have aligned more closely with the “resist” wing but performed almost as well as Kevin Jenkins, who ran in the last cycle.
County party chairs should pay attention. Their job includes growing their parties’ bases enough to influence district and statewide races. Johnson County Republicans appear to have done that, while Democrats have mostly lost ground.
Population changes add another dimension, but not a clear explanation. We cannot determine how new residents vote. Yet some Democratic candidates attract considerably more support than others despite growing Republican dominance. Their messages, individual appeal, and willingness to engage locally may still make a difference. Party affiliation alone doesn’t explain every variation.
The figures suggest a political landscape shaped by national realignment, demographic change, and individual candidates. Understanding those patterns will be increasingly important for county party chairs hoping to build support and influence future elections.
