Incumbent Pete Aguilar holds a commanding position in the California 33rd congressional district race due to his established record since 2015, substantial fundraising advantage exceeding $3.9 million, and leadership role as House Democratic Caucus chair. The June 2026 top-two primary reinforced this edge, with Aguilar securing over 53 percent while Republican votes fragmented among multiple candidates, allowing Stephanie Vargas to advance with roughly 17.5 percent. Forecasters rate the district as solidly or safely Democratic, consistent with its partisan voter index and recent election margins. Trader consensus reflects these structural factors ahead of the November 3 general election. A late-breaking scandal, significant health event, or unexpected national political shift could still narrow the gap, though no such developments have materialized.
