CIVIC HERALD

U.S. House · CA-10

This matchup isn't final yet — we haven't confirmed every candidate here against the state's official candidate list.

This candidate list comes from federal campaign filings. We haven't checked it against CA's certified ballot yet — someone on that ballot may be missing here, and someone here may not be on it.

An incumbent has a record; a challenger has statements. We show each for what it is.

HEAD-TO-HEAD · U.S. House · CA-10 · SAME SCALE, SAME METHOD, BOTH CANDIDATES

Two records. Your values.

Solid and hatched shapes are built from roll-call votes wherever a record exists — what each did, not what either says; a shape drawn from reviewed statements is marked on statements. Whose record sits closer to yours is your call to make.
