Republican primary night delivered a major political upset as Trump-backed challenger Ed Gallrein defeated longtime Kentucky Congressman Thomas Massie. The contest drew national attention because of its massive spending totals and Trump’s direct involvement in the race. The article argues the outcome signals continued dominance by President Trump inside the GOP, especially against incumbents viewed as disloyal or obstructive. Across several other states, Trump endorsements also appeared influential in gubernatorial and Senate races heading into the November midterms.
