Derek Tran holds a commanding position in the CA-45 race due to redistricting under Proposition 50 that added more Democratic-leaning areas in Los Angeles County, shifting the district's baseline toward a likely Democratic outcome according to forecasters. As the incumbent who narrowly won in 2024, Tran secured over 53 percent in the June primary and maintains a substantial fundraising edge exceeding $5 million compared to Chuong Vo's roughly $844,000. The district's large Vietnamese American population and top-two primary format further consolidate support for the sitting representative. Late shifts in turnout among key voting blocs or unexpected national developments could still narrow the margin before the November 3 general election.
