Polymarket prices Xavier Becerra at 93% to win, reflecting his commanding structural advantage in a state where Democrats outnumber Republicans 2-to-1 and no Republican has won statewide in 20 years. With Becerra securing the Democratic slot in the top-two primary against Republican Steve Hilton, the general election heavily favors the former HHS Secretary, despite Hilton's Trump endorsement and focus on affordability messaging. The 8% priced for Hilton reflects the narrow but non-zero path available to a Republican candidate if economic conditions deteriorate sharply or if Becerra encounters unexpected scandal before November.
