Republican fundraiser on Mitt Romney's problem: 'You run out of people you can hit up for $2,500'

BuzzFeed's Zeke Miller takes a look at a provocative question: is Mitt Romney's campaign on the verge of facing a cash crunch? Romney's campaign says everything is fine, pointing to recent fundraisers and a $1.3 million ad buy in Michigan, but Miller talks with several anonymous Republican fundraisers in New York who say Romney has a problem.

At the core of it? Romney's fundraising is extremely top heavy, relying overwhelmingly on big dollar contributors. Unlike President Obama, just 9% of Mitt Romney's financial support comes from small donors. A campaign can always resolicit small donors, but big donors are limited to $2,500—and as one Republican fundraiser told Miller: "You run out of people you can hit up for $2,500."

According to Miller, another GOP fundraiser said Romney is "tapping out" the donor network in big cities, where donors feel it is "embarrassing" to ask for money to help Romney beat Santorum given that (in their view) Santorum should be so easy to beat. Ultimately, the problem may come down to the simple fact that Mitt Romney is running a lackluster campaign. As another Republican fundraiser told Miller, Romney is "a Republican John Kerry running Hillary Clinton's campaign."

But don't feel too sorry for Mitt Romney. If money does dry up, there's always his Super PAC ... and short of that, I hear he's got a nice pile of cash tucked away in the Caymans. A rainy day fund, if you will.
