WASHINGTON (AP) — Calls for pragmatic centrism helped Joe Biden clinch the Democratic presidential nomination. But they left many of the party’s strongest liberals worried little progress would be made toward their sweeping goals. Biden’s campaign is discussing top issues with leading progressives to rectify that. The idea is to unify the party more than it was in 2016 when Donald Trump was elected. Any substantial move to the left may pull Biden away from the center that has defined a political career spanning nearly 50 years. That’s raising concerns Biden may be trying to be too many things to too many people and lose the ability to truly motivate a large chunk of them to turn out in November.
