Jonathan Easley reports at The Hill:
Vermont Sen. Bernie Sanders (I) is the country’s most popular active politician, underscoring his importance to the Democratic Party as it seeks to rebuild in the wake of a disastrous 2016 election cycle.
Sanders is viewed favorably by 57 percent of registered voters, according to data from a Harvard-Harris survey provided exclusively to The Hill. Sanders is the only person in a field of 16 Trump administration officials or congressional leaders included in the survey who is viewed favorably by a majority of those polled.
White House chief strategist Stephen Bannon is far and away the least popular political figure in the poll, with only 16 percent viewing him favorably, compared with 45 percent having a negative view of him.
