Senate Majority Leader Mitch McConnell ranked dead last on a recent poll of senators' popularity.
Exactly 55 percent of Kentucky voters disapprove of the lawmaker's job in office while one-third are content, according to Morning Consult poll released Tuesday.
The July 1-Sept. 30 survey found retiring Sen. Jeff Flake, R-Ariz., received the second-highest disapproval rating: 48 percent. Fellow Republican from Arizona, John McCain, had the third-highest disapproval score at 44 percent.
All three have publicly clashed with President Trump during his first nine months in office.
Sen. Bernie Sanders, I-Vt., received a 71 percent approval rating, the highest of the 100 senators. Sanders was previously ranked the most popular senator in the same poll earlier this year.
Sen. Patrick Leahy, D-Vt., took second place with a 67 percent approval score and Sen. John Hoeven, R-N.D., finished in third place with a 63 percent approval rating.
The online poll was conducted among 255,120 registered U.S. voters and residents from each state voted on their individual leaders. The survey's methodology page did not share a margin of error.
