Thomas Phippen of the Daily Caller reports on efforts to rebuild the national Democratic Party after its shocking 2016 presidential loss.

One year into his mission to fix the Democratic National Committee, chairman Tom Perez says the task is far more challenging than he anticipated.

“I knew it was a turnaround job when I ran, but I undeniably underestimated the depth of the turnaround job,” Perez told Politico. “We had to rebuild almost every facet of the organization, and equally importantly, we had to rebuild trust. Not just people who had invested in the DNC, but others, they just felt the party had let them down.”

The DNC has struggled to regain trust after reports former presidential candidate Hillary Clinton manipulated the structure to win the nomination over Vermont Sen. Bernie Sanders. Former President Barack Obama depleted the party’s funding to pay his own polling and consultants during his second term, and former chairwoman Rep. Debbie Wasserman Schultz of Florida is seen as a weak leader.

The chief challenge for the party is to regain trust and a strong network of local chapters. The organization became very much a top-down organization leading up to the 2016 presidential campaign, according to former interim party chair Donna Brazile.
