Washington (CNN) House Democrats on Thursday elected Rep. Cheri Bustos to serve as the next chair of the House Democratic campaign arm, the Democratic Congressional Campaign Committee.

Bustos represents a congressional district in Illinois that President Donald Trump won in 2016.

"We won a mandate from the American public from hard-working people to get results," Bustos said at a press conference following her win, referring to the party's midterm victory. But, she acknowledged, "We don't have the Senate. We don't have the White House," adding, "So it is now very important that we run a world-class political arm of the House Democrats. Absolutely imperative. We've got to take a look at every single district in this country. That's what we intend to do. Every battlefield will be protected and contested. That will be our role."

Bustos ran against Reps. Denny Heck and Suzan DelBene, both of Washington state. The vote totals were 117 for Bustos, 83 for Heck and 32 for DelBene.

Rep. Sean Patrick Maloney of New York had also been running for the post of DCCC chair, but he dropped his bid, an aide to the congressman confirmed to CNN on Thursday.
