What’s going on with the Democratic race? A new study from the Center for Working-Class Politics shows why the race is still neck and neck

Democratic National Convention in August was roundly acclaimed as a great success, presenting a unified front that stretched from Shawn Fain and Bernie Sanders to Adam Kinzinger and Leon Panetta .

A poll of 1,000 Pennsylvania voters shows that the campaign was tentatively heading in the right direction this summer .

It also suggests why, despite Donald Trump ’s efforts to alienate voters, the race is neck and neck.

Julian Zelizer : It's the People vs the Elites, Stupid! It’s not just working-class voters who feel that the country is headed in the wrong direction, Zelizer says.

He says trust in the political establishment has never been lower; fewer people than ever identify with either party; 70 percent of Americans believe that powerful interests are rigging the economic system; only 40 percent of lower-income Americans believe it is still possible to achieve the “ American dream”.

Julian Zelizer : Kamala Harris's campaign has turned to friends on Wall Street for campaign strategy.

He says the campaign has tried to distance itself from anything that even remotely smells of an anti-elite economic agenda.

Zelizer says the Democratic Party was never going to undergo a radical transformation over the course of a single presidential race.
