WASHINGTON - Former US president Bill Clinton believes a candidate with Republican Mitt Romney's business success and political background is qualified for the White House, but he said Democratic President Barack Obama would be a better choice for the country."There is no question that in terms of getting up and going to the office and basically performing the essential functions of the office, a man who has been governor and had a sterling business career crosses the qualification threshold," Clinton said of Romney in an interview with CNN on Thursday."But they have dramatically different proposals, and it's my opinion, anyway, that the Obama proposals and the Obama record is far better for the American economy and most Americans than those that Governor Romney has laid out," Clinton said of his fellow Democrat. "That's what the election ought to be about."Romney clinched the Republican nomination this week with a primary win in Texas although the race has been over for weeks as his remaining party rivals had suspended their campaigns.
