Primary elections in Kentucky, Georgia, Idaho, and Oregon and a special election in California proved to be a good night for some incumbents facing challengers from their own parties.

Rep. Thomas Massie (R-KY) easily won the GOP primary in Kentucky, fending off two Republican rivals, as did Rep. Lucy McBath (D-GA), who won a Democratic primary against two challengers in Georgia. In Idaho, Rep. Mike Simpson (R-ID) also survived GOP primary challengers.
