New outside groups that can raise unlimited cash are encroaching on the money, functions and talent of the Big Six — creating a shadow party system of super PACs and linked nonprofit groups unrestrained by the political sensitivities and fundraising limits that moderate the parties’ activities.
“It used to be that the party committees were the dominant force, and now that influence has been diminished by the super PACs,” said Ed Rendell, a former Pennsylvania governor and Democratic National Committee chairman. The outside groups, Rendell said, are “taking part of the responsibilities away from the parties and thereby diminishing the parties’ impact.”
