Methodology 

To identify the U.S. senators who are gaining in popularity, 24/7 Wall St. reviewed the percentage point change in approval ratings for all 100 U.S. senators from the first quarter of 2021 to the first quarter of 2022 from Morning Consult, a public opinion data research company. Senators are ranked by the one-year change in the share of their constituency who approve of the job they are doing. In cases where two or more senators have the same change in approval rating, the senator from the state where polls were taken from a larger sample size of registered voters ranks higher. 

All polling data was collected among registered voters in the state represented by the senator in question in the first quarter of 2021 and 2022. Approval ratings in this publication are rounded figures and may not exactly match those reported by Morning Consult.  

We also reviewed the share of voters who participated on election day in 2020 from the U.S. Census Bureau’s Current Population Survey.
