Sen. Ed Markey defeats Rep. Seth Moulton in Massachusetts' Democratic Senate primary, beating back a generational challenge as the 80-year-old incumbent seeks a third full term. Markey leaned into his support for transgender athletes competing in sports, drawing a sharp contrast with Moulton, who previously said he doesn't want his two daughters "getting run over on a playing field by a male or formerly male athlete." The longtime senator also had the backing of progressive heavyweights Bernie Sanders and Alexandria Ocasio-Cortez.
