The Vermont democratic socialist may have surprised the party’s establishment with his strong performance so far. He’s been polling second, behind only former Vice President Joe Biden, who has yet to enter the race. Sanders also took the lead in an Emerson poll released Tuesday. He raised more than $18 million in the first quarter of 2019, the most money of any Democratic contender. And his base of loyal followers, who made him a force in the 2016 primary, has not gone anywhere.
