And even the most well-funded campaign, that of Romney, also has relied heavily on super PAC spending.
"Mitt Romney is raising a lot of money through a super PAC because half of his donors are already maxed out and two thirds of his money has come from people who have maxed out," Malbin says. "He needs the super PAC because he doesn't have a broad donor base."
But there remains one fact in politicking that the super PACs haven't changed, Corrado says.
"It's still the case that money is essential to getting out the message, but it's still the message and the performance on the campaign trail that matters," he says.
