According to new poll, Sen. Bernie Sanders (I-VT) has the highest approval rating of any U.S. senator currently in office.

Sanders, who finished as runner-up to Hillary Clinton in the 2016 Democratic presidential primary, has a 75 percent approval rating from Vermonters, compared to a 21 percent disapproval.

He's followed by Patrick Leahy (D-VT) at 70 percent approval, John Barrasso (R-WY) at 69 percent, Michael Enzi (R-WY) at 68 percent, and Angus King (I-ME) and Susan Collins (R-ME) at 67 percent.

At the other end of the spectrum is Senate Majority Leader Mitch McConnell (R-KY)...

47 percent of Kentucky voters said they disapprove of McConnell, while 44 percent approve, making him the only senator with a net negative approval rating.

Although he retains the title of least popular senator, McConnell is at least trending in the right direction.

In September, more than half (51 percent) of Kentucky voters said they disapproved of McConnell, compared with 39 percent who approved of his performance.

John McCain (R-AZ) at 43 percent disapproval, Lindsey Graham (R-SC) at 40 percent, Lisa Murkowski (R-AK) at 40 percent, and Claire McCaskill (D-MO) at 39 percent round out the top five least popular.

Morning Consult polled over 85,000 registered voters across the nation between January 2017 and March 2017 to determine the rankings.
