“People are coming out of the woodwork,” said the fundraiser, who requested not to be named. “A number of my friends who didn’t want to get involved in the primary are now coming off the sidelines for the general election.”

The Romney supporter told The Hill that two recent fundraisers in Florida had netted more than $3 million combined, and said the moment Romney and the Republican National Committee entered into a joint fundraising operation a number of top GOP donors who had been resistant to giving decided to make major donations.

“This all started when we signed the contract with the RNC — that’s when the general election really began for us,” the fundraiser said. “There’s a lot of enthusiasm out there — I can in a week’s time raise $1 million for an event.”
