Former Vice President Joe Biden, former Agriculture Secretary Tom Vilsack and former Attorney General Eric Holder had backed Perez.
The resistance, of course, is the groundswell of opposition that President Trump, a Republican, has felt since taking office.
But when a party is out of power, as Democrats are now, the race for chairmanship reflects competition among rival factions over how best to re-orient the party for future elections.
Republicans occupy the White House, run both chambers of Congress and control about two-thirds of U.S. state houses.
Larry Cohen, the chairman of Sanders' new organization Our Revolution, and former head of the Communications Workers of America, said Perez "didn't win over anyone" on the Sanders-aligned left during the race for DNC chair.

In his speech to DNC voters before the voting, Perez said that all Democrats would leave united and that Democrats are the party of inclusion in every zip code.

Good or bad, this will prove to be a big deal for the Democrats moving forward as they fight Donald Trump's agenda!
Rep. Keith Ellison picked up a semi-endorsement from an expected - and potentially unwelcome - source Wednesday morning in his bid to become Democratic National Committee chair: Donald Trump.
Tom Perez, the most recent secretary of labor under Barack Obama, was elected the next chairman of the Democratic National Committee, after a contentious vote to lead the party after its devastating loss in November. Ellison said that the party has to go to the grassroots. "Our leadership is old and creaky, including me, and we've got to have this guy, 36 years old, running this party". That was smart. He wasn't likely to come close to either Perez or Ellison and that might have slowed the momentum and buzz he clearly built in the race. In order to secure the position, a candidate will need 224 of the total 447 party member votes.
