Democrats are scrambling to find a new head of the party just as they prepares to meet in Philadelphia to make Hillary Clinton the nominee.

Representative Debbie Wasserman-Schultz announced Sunday she was quitting her post, stunning the delegates and party operatives who are gathering here for their party's convention which kicks off Monday – following the leak of internal party emails that showed DNC meddling and favoritism toward Hillary Clinton.

One prominent name is already being floated: Housing secretary Julian Castro, who was high on Clinton's list to serve as her vice presidential running mate, CNN reported.

Castro is considered an articulate and telegenic spokesman, and has already appeared with Clinton on the stump on numerous occasions.

Clinton ultimately opted not to choose him, going for the more seasoned Virginia Senator Tim Kaine, who sits on the Senate Armed Services Committee and has amassed governing experience as governor of Virginia and past head of the DNC.

The party post might be a perfect chance for Castro to build up party experience and add some gravitas, after his relative youth hampered his chance of getting on the ticket. He is just 41 years old.

It wasn't known at press time whether Sanders forces, who are still sore about their candidate's defeat, would be comfortable with a DNC head so close to Clinton. The party just changed its rules on Saturday to limit the role of super delegates in a move Sanders championed.

'Debbie Wasserman Schultz has made the right decision for the future of the Democratic Party,' Sanders said in a statement released Sunday.

'While she deserves thanks for her years of service, the party now needs new leadership that will open the doors of the party and welcome in working people and young people,' Sanders continued. 'The party leadership must also always remain impartial in the presidential nominating process, something which did not occur in the 2016 race.'

The statement did not mention any potential candidates for the post by name.

Donna Brazile already serves as vice chair of the DNC, and will take over on an interim basis. She already has a good gig as a CNN commentator and political analyst

Another name that surfaced earlier this summer after Sanders delegates heckled Clinton supporters during a contentious Nevada state convention was Senator Richard Durbin of Illinois.

He is the party's whip, and is close to President Obama.

Senate minority leader Harry Reid floated his deputy's name when Wasserman Schultz was coming under fire.

'A lot of people put my name up but I didn't ask for any of this,' Durbin told CNN earlier this month.

Describing his conversations with Reid, Durbin said: 'He told me that he had mentioned it. That was as far as it went. There wasn't any active discussion. Nothing came of it.'

In the meantime, longtime party operative and party vice chair Donna Brazile will run the party on an interim basis.

Although she is a Clinton loyalist, she is viewed as more of as an honest broker by both factions, including forces loyal to Sanders who have groused about a 'rigged' system that gave the nomination to HIllary.

Talking to George Stephanopoulos on ABC's This Week, Brazile said this morning that she had already apologized yesterday to the Sanders camp.

'I think, the allegations, the emails, the insensitivity, the stupidity needs to be addressed and we are going the address it,' she said.

As the torch passed over to Brazile, Wikileaks quickly tweeted conversations in which the interim chairwoman was 'implicated' in the brewing scandal.

On such message has her passing along a request for comment from a Washington Post reporter saying that she wouldn't answer it because she would 'cuss out the Sanders' camp!'

A Twitter user responding to that tweet also found an email from Brazile in which she called a statement from the Sanders campaign 'stupid.'

Brazile is to serve through the November elections.
