The United States' 2026 midterms are less than eight months away, and Democratic strategists are feeling cautiously optimistic by what they're seeing. Many of their candidates have prevailed in recent elections in competitive swing states, some by double digits. And a Democratic nominee, Taylor Rehmet, enjoyed a 14 percent victory in a Texas State Senate special election in the conservative Fort Worth suburbs — an area that Donald Trump carried by 17 percent in 2024.MS NOW's Steve Benen, in a March 11 column, focuses on the results of a special election for a New Hampshire State Legislature seat held on Tuesday night, March 10 — which, he stresses, is yet another bad sign for Republicans ahead of the midterms.Democrat Bobbi Boudman defeated the Republican nominee, Dale Fincher, by 4 percent in a district that, according to the New Hampshire Journal, "voted Republican by more than 13 points just 16 months ago."Benen explains, "The New Hampshire Union Leader called the outcome 'stunning' and a 'big upset' given the Republican advantage in the local district. In a press statement, Democratic Legislative Campaign Committee President Heather Williams boasted, 'Tuesdays are becoming a headache for state Republicans across the country as they suffer one stunning defeat after another.' And therein lies the point: For Democrats, 2026 is off to a very encouraging start."Politically, New Hampshire is a much different state from neighboring Massachusetts. While Massachusetts is heavily Democratic, New Hampshire is more of a swing state. New Hampshire's current governor, Kelly Ayotte, is a conservative Republican, as was its last governor, Chris Sununu. Thus, Boudman's victory is a bigger deal in New Hampshire than it would have been in deep blue Massachusetts, especially in that district.The New Hampshire race, Benen observes, exemplifies a pattern that looks good for Democrats ahead of the midterms."In January," Benen notes, "two of the party's candidates won lopsided victories in two special elections in Minnesota, the first two contests of the year, restoring the state House to an even partisan split…. In early February, Republicans in Louisiana saw a unique opportunity to flip a state legislative seat from blue to red — in a district Trump won by 13 points — but when voters had their say, the Democratic candidate prevailed by 24 points." The "Rachel Maddow Show" producer continues, "Last week, a Democratic state legislative candidate also flipped a seat in Arkansas, reinforcing the larger pattern…. Some will no doubt argue that it’s best not to read too much into a special election held in the winter, several months before November's races. It's a fair point, to be sure. But what matters is the degree to which the results fit into the broader political landscape…. If party insiders aren't concerned about their standing ahead of this year's midterm elections, they're not paying close enough attention."
