Senate Minority Leader Chuck Schumer, D-N.Y., is trying to reboot the Democratic brand and urged the party to "look in the mirror" and focus on an economic agenda in the weeks ahead.

Schumer told ABC's "This Week" Democrats will be rolling out a new economic platform this week — titled "A Better Deal" — aimed at "working voters," including those who spurned the party for President Trump in November.

"It is, in part, our fault," that voters don't know what Democrats stand for, Schumer said. "When you lose an election with someone who has, say, 40 percent popularity, you look in the mirror and say, 'what did you do wrong,' and the No. 1 thing we did wrong is we didn't tell people what we stood for. Even today, as your polls show, they know we're standing up to Trump. They like that, but they want to know, 'what do you stand for.'"

"I don't know why it didn't happen in the campaign. We all take blame, not any one person," Schumer said.

Schumer's comments came after an ABC News/Washington Post poll revealed only 37 percent of voters believe Democrats "stand for something," while 52 percent say they only are standing up against Trump.

"Week after week, month after month, we're going to roll out specific pieces here that are quite different than the Democratic Party you heard in the past," Schumer said. "We were too cautious. We were too mamby-pamby."

"This is sharp, bold and will appeal to both the old Obama coalition ... and the Democratic voters who deserted us for Trump, the blue-collar workers. Economics are our strength, and we are going to go at it," Schumer added.
