We’re over halfway through primary season. Here’s what the battlegrounds tell us.

Two-thirds of the way through primary season, results from dozens of hotly contested battlegrounds across the country reveal a Republican Party that remains fully captured by President Donald Trump, even in swing districts that have at times rejected his brand, and a Democratic Party that is still consumed by factional infighting over how to win. The midterms will help give the party clues about what kind of Democrats are best poised to win ahead of 2028 -- but it has also turbocharged an ideological civil war between the different wings of the party, especially as progressives have gained ground in both deep-blue and battleground districts.
