Since launch

None yet.

During the preview, before launch

Before the site opened to the public, we reviewed every match between a survey question and a vote. These are the fixes that changed what a reader would have seen.

November 8, 2026

• Children's health insurance (CES 2008). The question was compared with the February 2007 passage of H.R. 976, which at that point was an unrelated small-business tax bill. It is now compared with the bill's final votes in September 2007 (House 265–159, Senate 67–29).
• Help for homeowners facing foreclosure (CES 2008). Senators were compared on the Senate's April 2008 vote on an earlier draft. They are now compared on its final vote of July 26, 2008 (72–13).
• Trade agreement with Peru (CES 2008). The House vote matched to this question was corrected to the House's passage of the agreement.
• House health care bill (CES 2009). The bill number, H.R. 3962, was later reused for an unrelated Medicare bill (June 2010, 417–1), and that vote was also being matched. Only the November 2009 passage vote is compared now.
• Senate votes of 2015–2016 (114th Congress) were missing. The source file wrote member IDs in a different format, so none of its 502 votes loaded. All are loaded now.
• Appointed senators shown as former members too soon. A senator appointed to fill a vacancy was listed as former once their appointment's listed end date passed, even before a successor was recorded. They now stay listed as serving until a successor appears in the member list.

November 7, 2026

• TikTok bill (CES 2024). The House passed H.R. 7521 under a suspension of the rules, which the matching rule didn't recognize, so representatives weren't compared on it. They are now.
