Fred Barnes, writing in the Wall Street Journal:
"Mitt Romney is rolling to the Republican presidential nomination. He's the first Republican other than a sitting president to win both the Iowa caucuses and the New Hampshire primary. Yet he just began confronting the greatest threat to his quest for the presidency—an explosive issue that could diminish the Republican Party's prospects for defeating President Obama.
"The issue is Mr. Romney's record as an investor and corporate-turnaround artist at Bain Capital from 1984 to 1999. That experience is the heart of his campaign for the White House, the source of his claim to be uniquely qualified to invigorate the economy and create jobs....
"Mr. Romney bears some of the blame for the awkward situation. Candidates for president normally build their campaigns on a big idea. Mr. Gingrich's is that he would crush Mr. Obama in debates and win the election. Mr. Perry's is that he would extend the economic success of Texas to the entire nation. Mr. Romney's is himself, the man whose skill at economic revival was on display at Bain. This is an invitation to attacks.
"What Mr. Romney needs is a bigger idea to deflect attention from Bain. He's treated the economy as susceptible to his personal care. That's insufficient. A bold plan for economic growth, especially a controversial plan with sweeping tax reform, might work. But if not that, then at least do something that dwarfs Bain—and do it soon."
Whole thing here.
