Priorities announced last month that it raised $6 million in June, the largest ever single-month haul for the group. Donors included actor Morgan Freeman, who gave $1 million.
But that total was dwarfed by Restore our Future, the pro-Romney super-PAC that quadrupled its haul between May and June and raised a record $20 million. Half that total came from a $10 million single-check donation from casino mogul Sheldon Adelson, who has spent heavily to support Republicans this election cycle.
Other Republican groups — including Karl Rove's American Crossroads and Crossroads GPS — also look to be prominent players, having already spent tens of millions on advertising.
