Maybe Romney understands financial hardship after all. In the waning months of the primaries, even when he was so often referred to as the “presumptive Republican nominee,” Mitt Romney’s presidential campaign borrowed $20 million, a senior campaign official confirmed Tuesday. Although Romney’s campaign had already raised hundreds of millions of dollars for the general election, election law prevented him from spending any of it until he became the official nominee. To compete with Obama’s cash flow, the campaign borrowed $20 million in August from the Bank of Georgetown. Thus far, $9 million has been paid back. The move is permitted by the Federal Election Commission.
