Romney may be running low on cash.

Hmmmmm.

"The former Massachusetts governor’s gold-plated fundraising machine has depended almost exclusively on big checks from the wealthy individuals — business leaders, Mormon allies, longtime Republican Establishment donors — whom Romney and his team have been cultivating for years, pressing the cases that resonate for those crowds: That he’ll cut taxes; that he’ll beat Barack Obama; that he’s inevitable and they’d better get on board.

But Romney has proved unable to tap into the emotion-drived small-dollar contributions that helped power Barack Obama in 2008, and which fueled even his more Establishment rival, Hillary Clinton, this time four years ago when she too began to run out of big donors. The result: Republican fundraisers say that despite his success so far, they think Romney is fast approaching a wall, and that he will likely be forced to pay for the campaign out of his own deep pockets."
