Mitt Romney's weekend swing through some of the country's toniest zip codes netted the presumptive GOP nominee a cool $7 million, his campaign said Saturday, though Romney himself said he'd rather be out on the stump than talking to donors.

"That's a challenge with a president who blew through the federal spending limits," Romney said aboard his campaign plane Saturday, as he hopped between two Massachusetts vacation spots, Nantucket and Cape Cod. "It means that campaigns now have to spend a disproportionate amount of time fundraising. You appreciate all the help you get, but you wish you could spend more time on the campaign trail."

In 2008, then-candidate Barack Obama broke all fundraising records, bringing in roughly $750 million to his campaign coffers. He was accused by his challenger, Sen. John McCain, of breaking a promise when he announced in June 2008 he would forgo the $85 million in public funds available to presidential candidates - and consequently free himself from federal campaign spending limits. McCain accepted the federal funds and stayed within the federal spending restrictions.

Romney's effort has out-raised the Democrats for the past three months, including in July, when his campaign and the Republican National Committee brought in a total $101.3 million.

On Friday and Saturday, Romney boosted the campaign bank account with events in Southampton, New York, and in Martha's Vineyard, Nantucket, and Cape Cod, Massachusetts.

On Friday, Romney shared coconut shrimp skewers and duck samosas at the Sebonack Golf Club on the eastern end of Long Island with campaign supporters, including Woody Johnson, the owner of the New York Jets, and Steve Ross, who owns the Miami Dolphins. The fundraiser brought in $3.25 million for the Republican candidate.

Saturday saw Romney island-hopping off the coast of Massachusetts, hitting fundraisers on Martha's Vineyard ($2,500 for the reception, $25,000 for a photo, $50,000 for the VIP event), Cape Cod ($25,000 for a photo, $50,000 for VIP reception), and Nantucket ($2,500 for cocktails, $10,000 for the VIP reception).

Hosting the events were some prominent Republican backers: Jack Welch, the former chairman of General Electric; former Senate Majority Leader Bill Frist; and Bill Koch, a businessman whose brothers Charles and David are major backers of conservative and libertarian causes.

Obama is himself no stranger to high-dollar fundraisers, including in some of the country's ritzier neighborhoods. Earlier this year he brought in an estimated $15 million at George Clooney's home in Los Angeles, and he attended a high-dollar event at Sarah Jessica Parker's townhouse in New York City's West Village in June, bringing in an estimated $2 million.
