Democrats lag in super PAC race for million-dollar contributions

The top “super PACs’’ supporting Republicans in the fall elections have raised more than three times as much money as super PACs aligned with Democrats, $158 million to $47 million, a Globe analysis shows.
The imbalance comes as well-to-do Republicans have been far more generous than their Democratic counterparts, more frequently tossing as much as $1 million or more into the GOP cause.
Unless things change in the next four months, the gap could cost the Democrats the White House and both houses of Congress, no less an authority than President Obama said in a conference call to major Democratic donors late last week.
