Even as approval ratings continue to fall in the Senate, Sanders has remained on top — while everybody hates Mitch, according to a new Morning Consult poll. The longest-serving independent in Congressional history holds a 75 percent approval rating among his constituents and only a 21 percent disapproval rating, according to the poll. That gives Sanders the highest approval rating in the Senate. In second place is Sen. Brian Schatz, D.-Hawaii, with 69 percent of his constituents approving of his job. Senators Mazie Hirono (D.-Hawaii), John Hoeven (R.-N.D.) and Patrick Leahy (D.-Vt.), rounded out the top five. Sanders was also named the most popular politician in the entire country in a March 2017 Fox News poll. In that poll, he held a 61 percent approval rating among those polled across the country.
