Romney's campaign cited campaign disclosure reports showing that the article's author, Reed College economist Kimberly A. Clausing, has donated money to Obama's campaign. Republicans say Romney's overall tax proposals would encourage greater job growth at home.
Romney "has a comprehensive plan to reform the corporate tax code that will lower rates, get rid of incentives for firms to create jobs in other countries, and encourage the kind of economic growth President Obama has been unable to deliver," said campaign spokeswoman Amanda Henneberg.
For all the tax talk, the presidential campaign couldn't seem to shake Bain, the company that Romney led in the 1990s to numerous successful corporate restructurings, and to some less happy ventures that ended in bankruptcy or other problems.
Romney has said he left Bain in early 1999, shortly before it invested in companies that were pioneers of job outsourcing. Romney says he played no role in those transactions and decisions.
Two years later, however, Bain was still filing disclosure documents with the Securities and Exchange Commission that named Romney as the firm's CEO, president, sole shareholder and "the controlling person." At least one document in early 2001 said Romney's "principal occupation" was as Bain's managing director.
Bain says it took some time for disclosure forms to catch up with management changes at the firm. Romney says he was working fulltime on the Winter Olympic Games starting in early 1999. Democrats say Romney has yet to satisfactorily explain.
Romney traveled to Louisiana to attend a private fundraiser alongside Louisiana Gov. Bobby Jindal, who is among those on Romney's short list for vice president. Romney raised an estimated $2 million at the event, where 40 donors paid $50,000 to attend.
Jindal has been campaigning aggressively for Romney in recent weeks, as have others thought to be under consideration. They include Ohio Sen. Rob Portman, former Minnesota Gov. Tim Pawlenty, Wisconsin Rep. Paul Ryan and Florida Sen. Marco Rubio.
Obama raised at least $625,000 at his own fundraiser at the Cincinnati Music Hall before his public appearance.
While Romney and pro-Republican "super PACs" are raising huge sums, campaign laws place limits on how much Romney can spend before the late-summer nominating conventions take place. Meanwhile, Obama has outspent Romney in some key states.
