CA-10 — U.S. House

How competitive is this race?

Three independent forecasters rate every race from Safe to Toss-up. This is their judgment, not ours, and not a poll. Where they disagree, that disagreement is the information.

Rated Safe for the party that holds the seat by all three forecasters. None of them lists it as competitive.

This list is who filed with the FEC and raised money — it is not a certified ballot. The FEC has no ballot-access data; that sits with each state. Candidates who lost a primary can still appear here until a state ballot feed is added. Ordering is by money raised, which is a fact about filings, not a judgment about who is likely to win.
