Sen. Bernie Sanders (I-VT) is the most popular senator among his constituents in the country, according to a poll released Tuesday. Senate Majority Leader Mitch McConnell (R-KY) is the least popular.

Seventy-five percent of Sanders’ constituents approved of his performance in office, compared to 21 percent who disapproved, according to the latest installment of Morning Consult’s senators poll.

Forty-four percent of Kentuckians approve of McConnell’s performance, compared to 47 who disapprove. McConnell is the only senator to receive a net disapproval from his constituents, Morning Consult found.

Sanders and McConnell retained their titles as most- and least-liked since the last time Morning Consult released poll results on senators’ approval ratings among constituents, in September 2016.

Morning Consult polled more 85,000 registered voters in weekly online polls from January through March 2017, according to its website, which did not include a margin of error. They weighted results for gender, age, educational attainment and race.
