Joe Manchin represented West Virginia in the U.S. Senate from November 2010 to January 2025. He won three Senate elections (2010 special, 2012, 2018) in a state that has trended sharply Republican federally. As the most conservative Senate Democrat, he held effective veto power over the Biden administration's legislative agenda when Democrats had 50-vote control (2021-2023). He switched party affiliation to Independent in May 2024 and did not seek re-election. His tenure shaped the IRA, killed Build Back Better, and blocked the filibuster carve-out for voting rights.
Joseph Manchin III kept 10 out of 17 graded promises during his tenure, but broke three significant ones. He promised to pass voting-rights legislation and did not. He promised Universal Pre-K and expanded childcare—both failed. He promised to codify abortion rights and support Roe v. Wade, and that promise also did not materialize. Three additional promises were only partially kept.
On the promises he did keep, Manchin followed through at a rate of about 59 percent overall.
We don't yet have detailed donor data or voting records linked to specific bills in this cycle, so we cannot show which industries funded him most heavily or how his votes aligned with those funders' interests. That information would help complete the picture of his tenure.
