The United States Senate is more politically polarized than it has been in decades. According to analysis by the Pew Research Center, the ideological gap between Republican and Democratic senators is wider now than it has been at any point in at least the last 50 years. And growing partisanship has coincided with a sharp decline of legislative activity on the Senate floor. 

Government records show that the Senate spent an average of 999 hours in session per year between 2013 and 2022, down from an annual average of 1,163 hours from 2003 to 2012. Additionally, the Senate passed 1,489 public laws in the last 10 years, 617 fewer than in the preceding 10 years. 

While passing a bill through a divided Senate requires collective action, all sitting senators have the constitutional power to unilaterally propose new legislation by sponsoring a bill. Bills that originate in the Senate may be for the benefit of certain constituencies or the country at large. And even though most Senate bills do not become law, some senators appear less willing to make the effort to draft and introduce bills than others. 

Using historical records from the federal government’s congressional database, 24/7 Wall St. identified the 41 U.S. senators who are doing the least. Senators are ranked on an equally-weighted index composed of the number of bills they sponsored between January 2019 and October 2023 and the number of those bills that became law. Only the 81 senators who have been in office since 2019 or earlier were considered. 

Of the 41 senators on this list, 18 are members of the Democratic Party, 20 are Republicans, and three are independent. Between January 2019 and October 2023, only one senator on this list has sponsored over 300 bills. At the same time, no senators have had more than four sponsored bills signed into law, and 10 have not sponsored a single bill that became law. (Here is a look at the 24 members of congress who did not last 100 days in office.)

While the senators on this list have introduced and passed fewer pieces of legislation than many of their colleagues, some have additional responsibilities, either chairing or sitting as ranking members in a nonpartisan committee, often an indication of seniority and areas of expertise. This list includes the Senate Budget Committee Chair, Sheldon Whitehouse, a Democrat from Rhode Island, as well as Susan Collins, a Republican senator from Maine who serves as the ranking member of the Senate Appropriations Committee. 

Each senator on this list must win reelection to remain in power, and though voter sentiment is influenced by any number of factors unrelated to bill proposals, many of these senators are not especially popular. Based on a survey conducted by public opinion research company Morning Consult in the second quarter of 2023, 21 of the senators on this list had approval ratings below 50% – and of those, 11 are up for reelection in 2024, should they choose to run. (Here is a look at the least popular senators in America.)

Methodology

To identify the 41 U.S. Senators who are doing the least, 24/7 Wall St. reviewed historical data from the federal government’s congressional database. We ranked each of the 81 sitting U.S. Senators who have been in office since 2019 or earlier on an equally-weighted index composed of the number of bills they sponsored between January 2019 and October 2023 and the number of those bills that became law. 

We also reviewed supplemental information on the senators who either chair, or are ranking members of, a committee in the current 118th Congress. Only committees with no party affiliation are listed. 

Additional supplemental data on each senator’s approval rating is from public opinion research company Morning Consult, and is current as of the second quarter of 2023.
