SuperPACs are specifically forbidden from coordinating with campaigns on expenditures. To do so would be a epic -level FUBAR that only an idiot would do.
Does that mean staffers with several layers of insulation from the candidate don’t make off-hand “You know what would help us” comments over drinks? You have to be a special kind of naive to believe that doesn’t happen.
Again, though, nothing in FEC regulations prevents a SuperPAC from donating to multiple campaigns.
