WASHINGTON — Democrats have elected Florida congresswoman Debbie Wasserman Schultz as the new chair of the Democratic National Committee.

President Barack Obama picked the four-term lawmaker from South Florida last month to succeed former Virginia Gov. Tim Kaine, who is seeking a Senate seat in his home state.

The full DNC unanimously ratified Wasserman Schultz's selection on Wednesday, making her the first woman elected chair by the full body. Wasserman Schultz says she will "make sure that no one outworks the Democratic Party."

As DNC chairwoman, Wasserman Schultz is expected to play a key role in Obama's re-election campaign, helping Democrats define Republican presidential rivals and serving as a top advocate in Florida, one of the nation's top battleground states.
