ATLANTA—Former Labor Secretary Tom Perez was elected chairman of the Democratic National Committee on Saturday, giving the party an establishment leader at a moment when its grass-roots wing is insurgent.
Mr. Perez defeated Minnesota Rep. Keith Ellison and four other candidates in a race that had few ideological divisions yet illuminated the same rifts in the party that drove the acrimonious 2016 presidential primary between Vermont Sen. Bernie Sanders and former Secretary of State Hillary Clinton.
Mr. Perez’s victory capped a drama-filled afternoon. The former Labor secretary fell one vote short of a majority on the first vote for chairman, with Mr. Ellison 13 votes behind. The four second-tier candidates then dropped out of the race. On the second ballot, Mr. Perez won 235 of 435 votes cast.
As Donna Brazile, the outgoing party chairwoman, announced the final results, a group of green-clad Ellison supporters in the meeting hall drowned her out with chants of “not big money, party for the people.”
Mr. Perez played down divisions within the party, proclaiming his “love for the robust discussions that occur in the Democratic Party.” He added: “We need every house call, we need to listen to people, we need to get back to basics and we need to move forward.”
To help heal the division, Mr. Perez in declaring victory immediately appointed Mr. Ellison as the party’s vice chairman. Mr. Ellison practically begged his supporters to remain in the party and back Mr. Perez.
“If you came here supporting me, wearing a green T-shirt,” he said, “I’m asking you to give everything you’ve got to support Chairman Perez.”
President Donald Trump took a shot at Mr. Perez in a tweet about the Democratic vote. “Congratulations to Thomas Perez, who has just been named Chairman of the DNC. I could not be happier for him, or for the Republican Party!”
Mr. Perez tweeted in return: “Call me Tom. And don’t get too happy. @keithellison and I, and Democrats united across the country, will be your worst nightmare.”
