The Clinton brand of centrism is now in danger of dying off. Not only is the party more liberal than it was in the 90s, it’s more liberal than it was in 2008, the last time Hillary Clinton ran for the White House.

Forty-seven percent of self-identified Democrats describe themselves as economic and social liberals, according to a Gallup poll released last June. That’s up from 39 percent in 2008 and 30 percent in 2001, the year Bill Clinton left office.

The rapid change in the party has alarmed some centrist Democrats, who fear the party risks defeat in November by moving too far out of the mainstream on economic issues.

“Democrats, from the progressive left to the center, are mostly united on these social issues. That wasn’t the case 20 years ago, and we’re very, very happy about it,” said Jim Kessler, senior vice president for policy at the center-left think tank Third Way.

“But on these economic issues, if the party moves too far left, Donald Trump will be president.”
