The race to become the Democratic National Committee chairman narrowed on Thursday when South Carolina Democratic Party Chairman Jamie Harrison dropped out, endorsing frontrunner Tom Perez in the process. Perez served as labor secretary under former President Barack Obama and holds about 205 of the 447 total DNC member votes. Rep. Keith Ellison (D-Minn.), backed by Sen. Bernie Sanders (I-Vt.) and the party's more progressive wing, trails Perez with around 153 votes.
"With so much at stake, our next chair will lead the fight of a generation," Harrison said in an email to NBC. "I'm standing by Tom Perez's side, and I hope you will join me in doing the same."
If Perez picks up at least 20 of Harrison's 27 votes, he will likely have a majority heading into the first round of voting Saturday. The winner needs only to win a simple majority of 224 votes or more; if no candidate achieves a majority Saturday, DNC members will cast votes in progressive rounds, eliminating the lowest vote-receiving candidates until a candidate emerges with the majority.
On Wednesday night, all of the DNC candidates went head-to-head in a CNN debate. You can watch a 90 second recap of what unfolded here.
