Approval is the latest published Morning Consult rating, from its quarterly survey of registered voters in each state. Last election is the share of the vote the senator won. Cash on hand is the campaign’s money at the end of the reporting period named.

Leadership posts
  • President pro tempore of the Senate, 119th Congress
  • Chaired the Judiciary Committee, 119th Congress
Committees
  • Judiciary
  • Agriculture, Nutrition, and Forestry
  • Budget
  • Finance

A gold mark names a leadership post. The posts and committees are the 119th Congress’s, as senate.gov lists them: a chair led a full committee for the majority, a ranking member was the senior member of the minority on it. The 120th Congress, which Democrats control, names its own in January 2027.

The filibuster

The senator’s own public position, from a recorded vote or a dated statement. A talking filibuster requires senators to hold the floor to block a vote.

Ending the legislative filibuster

Opposes

“The filibuster is very important to promote bipartisanship.”

A talking filibuster

Opposes

Voted against the January 19, 2022 rules change that would have required a talking filibuster on the voting-rights bill.
