(CNN) - The founder of Restore Our Future, a super PAC supportive of Mitt Romney, said Thursday the group saw money pour in one day after the GOP nominee pulled a widely applauded performance in the first presidential debate.
"I think that today will probably be the best fund-raising day we've had, if not one of the top two fund-raising days we've ever had," Charlie Spies said on CNN's Erin Burnett "OutFront."

While he did not give specific numbers, Spies said "people are fired up, they're energized and very excited."
The group has raised $96.7 million as of August 31 and has spent $86.6 million in the 2012 federal elections, according to Federal Election Commission reports. In recent weeks, Restore Our Future has aggressively targeted the battleground states of Wisconsin and Michigan, injecting millions of dollars in ads in the states.
Also Thursday, Romney's spokeswoman Andrea Saul tweeted that the campaign received "more than two donations every second" after Wednesday night's debate.
Meanwhile, senior strategist for a pro-Obama super PAC, Priorities USA Action, also said the group saw a spike in fund-raising after the debate, though not quite as much as Restore Our Future.
"Today was a pretty good day for us," Bill Burton said on "OutFront."
"Not top one or two?" Burnett asked.
"It was definitely a top five. I don't know about top one or two," he replied.
