California’s 45th congressional district held its June 2 top-two primary, pitting incumbent Democrat Derek Tran against five Republican challengers in an Orange County seat with a sizable Asian American electorate. With most ballots counted, Tran exceeded 50 percent of the vote and advanced automatically, while Chuong Vo led Republicans for the second general-election slot ahead of Chi Charlie Nguyen and others. Remaining vote-by-mail ballots continue to arrive but are unlikely to alter the outcome given current margins. Trader pricing on prediction markets reflects this near-certain advancement for Tran and the competitive positioning among Republican contenders. No further primaries or procedural hurdles remain before the November general election.
