Two of California’s most prominent Republicans have returned to the political stage to oppose Gov. Gavin Newsom’s (D-CA) statewide campaign to get voters to approve new congressional districts.

Former House Speaker Kevin McCarthy and former Gov. Arnold Schwarzenegger are using their considerable clout to raise money and speak out against Proposition 50, a November ballot measure that would approve a new congressional map passed by the state legislature last week and possibly give Democrats five additional House seats. The push for new maps is a direct response to Texas redrawing its map in favor of Republicans at the request of President Donald Trump, who is seeking to hold on to power during next year’s midterm elections.
