When it comes to Senate popularity, you can't beat Vermont's Bernie Sanders.
Sanders, who is one of two candidates for the 2016 Democratic presidential nomination, is the most popular U.S. Senator among his constituents, according to an analysis by Insidegov.com.The rankings were determined by interviews with more than 62,000 registered voters from Jan. 8-April 17.
Alabama's senior Senator, Richard Shelby, came in at number 20 on the list. Shelby had an approval rating of 59 percent and a disapproval rating of 28 percent. First elected to the Senate in 1986, Shelby made the switch to the Republican Party in 1994. He currently serves as the chairman of the powerful Committee on Banking, Housing and Urban Affairs.
How does that compare to Sanders' numbers? The self-described "democratic socialist" posts an 80 percent approval rating among Vermont voters with a disapproval rating of only 17 percent.
