Democrats embrace super PACs, but some fear lack of focus on midterm elections

The Washington Post reports:

As Democratic officials rely more than ever on the big-money super PACs they once scorned, party strategists and donors are caught in sharp disagreements over how to use the newly influential independent organizations.

Tensions are simmering over whether Priorities USA Action and other Democratic groups that can accept unlimited contributions are too focused on the 2016 presidential race and a potential Hillary Rodham Clinton candidacy, even as Democrats face a costly, uphill fight this year to retain a thin Senate majority and gain seats in the House.
