Why challengers have no voting record here

Only people who have held the office have cast roll-call votes, so a voting record exists for the incumbent alone. We do not fill that gap with campaign-website summaries or third-party scorecards: deciding which vote counts as “the” vote on an issue is an editorial act, and two advocacy groups routinely produce opposite grades from the same record.

What is on the record for every candidate equally is money — who funds them, and who is spending independently for or against them. Each name above links to that candidate's FEC filings.
