But most of those [super PACs] aligned with specific presidential candidates have already said how much they raised between January and the end of June. So far, they account for roughly $2 of every $3 given in the 2016 presidential race, with the vast majority of those donations aimed at helping Republicans win back the White House.

Less than 9 percent of the money given to candidate-specific super PACs so far will benefit Clinton and her rivals for the Democratic nomination, according to an Associated Press analysis. The AP compared money raised by formal presidential campaigns with what the super PACs say they plan to report having raised on Friday.
