The largest liberal “super PAC” in the country has begun raising money to elect Hillary Rodham Clinton president, formally aligning itself with Mrs. Clinton’s undeclared presidential ambitions more than two years away from the election.
The group, Priorities USA Action, which played a pivotal role in helping re-elect President Obama, also named new directors to steer the organization, appointments that will both cement the group’s pro-Clinton tilt and thrust veterans of Mr. Obama’s political and fund-raising operation into the center of the post-Obama Democratic Party.
