Bill Clinton's winning campaigns for the White House operated on the basic premise that, "It's the economy, stupid." But last year, it was Donald Trump who appealed to working-class and rural voters — those the Democrats now call "left out and left behind" by economic changes. Their new slogan, "A Better Deal," starts with increased wages, lower drug prices and the end of corporate mergers. Polls show Democrats are the party against President Trump, but to win elections they have to favor something, too. We hear what they want it to be.
