Rep. Ed Case defeated a primary challenger in Hawaii's 1st District, the Associated Press projected, defying a recent trend of progressive challengers ousting moderate incumbents. With 91% of the vote counted, Case had a nearly 14-point lead over his nearest challenger, state Sen. Jarrett Keohokalole. Case has represented Hawaii's 1st Congressional District, which includes Honolulu and other parts of Oʻahu, since 2019, having previously represented the 2nd District, which includes more rural parts of Oʻahu and the other islands, from 2002 to 2007. Given Hawaii's strong Democratic leaning, Case is favored to win in November. Democratic incumbents in safe districts in New York and Colorado have been ousted so far this year by primary challengers.
