The U.S. Congress is the least trusted government instituion by the American people. According to a recent poll by public opinion research company Morning Consult, a public opinion research company, only 39% of adults in the U.S. express at least some trust in Congress. This figure is lower than that of all five other public sector institutions covered in the survey, including the Supreme Court.

It may come as no surprise that there are excessively negative views of the U.S. legislature. A study published by the Institute for Policy Research at Northwestern University indicated that partisan conflict leading to legislative gridlock, especially on consensus issues, significantly diminishes public opinion of Congress.

Partisanship on Capitol Hill has been escalating for decades. According to analysis by the Pew Research Center, the ideological gap between Democratic and Republican congressional representatives is more pronounced today than at any other point in the last 50 years. This trend is particularly evident in the U.S. Senate.

While partisanship in the U.S. Senate has eroded public confidence in the institution, a number of individual lawmakers have succeeded in improving their standing with voters in recent years, going against the prevailing trend.

Using survey data from Morning Consult, 24/7 Wall St. identified the sitting U.S. senators who are gaining popularity. Senators are ranked on the percentage point change in their approval rating over the two-year period from the second quarter of 2021 to the second quarter of 2023. Only senators with approval ratings that gained at least 2 percentage points since mid-2021 were considered. 

Among the 33 U.S. senators listed, 20 are Democratic, 12 are Republican, and one is an independent. Thirteen of these senators are eligible for reelection in 2024 if they decide to run. Among them, approval ratings have seen an increase ranging from 2 percentage points to 15 percentage points over the past two years.

To identify the U.S. senators who are gaining popularity, 24/7 Wall St. reviewed the percentage point change in approval ratings for all 92 sitting U.S. senators in mid 2021. Senators are ranked on their increase in approval rating from Q2 2021 to Q2 2023, based on data from Morning Consult. In cases where two or more senators have the same change in approval rating, senators are listed in alphabetical order by the state they represent. 

Supplementary data on the share of registered voters who participated on election day in 2022 from the U.S. Census Bureau’s Current Population Survey.

Despite the increase in approval ratings, not all senators listed here enjoy widespread popularity. However, the majority of senators on this list are well regarded by their constituents, particularly when compared to many of their Senate colleagues. With the exception of 10 out of 33 lawmakers experiencing the most significant popularity growth, all others hold positions within the top 50% of all 100 sitting U.S. senators based on approval ratings. This includes seven of the 10 most popular senators.
