Today’s special election runoff in Georgia between Republican Clay Fuller and Democrat Shawn Harris to determine the successor to former Rep. Marjorie Taylor Greene (R-GA) isn’t much in doubt. The northwestern Georgia district that Greene represented backed President Donald Trump by 37 points in 2024, one of the largest GOP margins in the country.

What makes the otherwise sleepy contest significant is the potential for the results to indicate if there are any fissures within the MAGA coalition, ones that may represent Republican discontent with Trump’s hawkish turn amid the Iran war. In this race, the margins will be as notable as the winner. 

Greene, since leaving Congress, has emerged a loud Republican voice against the Iran war and against Trump’s strong alliance with Israel. Fuller, a military veteran with a background in counterterrorism operations and district attorney for the Lookout Mountain Judicial Circuit, has been a stalwart supporter of Trump’s military operations in the Middle East, and Trump has endorsed him in the race.

Harris, the Democrat, holds foreign policy views closer to the isolationist Greene, attacking the pro-Israel advocacy group AIPAC and describing Israel’s war against Hamas as a “genocide” — views which place him on the left flank of the Democratic Party. This despite Harris’ time serving as defense attache in Israel during his years in the National Guard, work history that he has not publicized during the campaign.

It’s worth noting that Greene, since she was first elected to the seat in 2020, has underperformed Trump’s standing in the district, only winning 64% of the vote against Harris in 2024 — four points below Trump’s 68% showing at the top of the ticket. And since breaking with Trump in his second term, her political standing has taken an even bigger hit.

Greene has not endorsed either candidate in the race.

If Harris wins over 40% of the vote in this ruby-red district, it’s a sign that Democrats are making inroads into rock-ribbed conservative turf, potentially over frustrations with rising gas prices and the Iran war. But if he doesn’t perform much better than he did in 2024 — and he only won 37% of the vote in the first round of balloting, compared to the 36% he tallied two years ago — it’s a sign that the media hype over a MAGA fissure is greatly overstated. 

The election also carries some relevance for another big political showdown in Georgia later this year: Sen. Jon Ossoff’s (D-GA) reelection campaign. Given a divided GOP primary field and an unfavorable national environment for Republicans, Ossoff starts with some advantages in what otherwise looks like a tough reelection.

If the GOP base turns out strongly for Fuller, it’s a sign that Republicans will still be able to rely on conservative voter enthusiasm and engagement in the run-up to the closely watched Senate battleground.

But if there are signs of GOP weakness in one of the reddest parts of the state, it would be evidence that Trump’s political problems aren’t just limited to swing voters, but could extend to even redder states and districts on the battleground map.
