NASHUA, N.H. — Forget his specific rivals. The biggest threat to Mitt Romney is hitting now and set to fully detonate in South Carolina: It’s the Bain bomb.While conservatives look unlikely to unite around one alternative to Romney, the campaigns themselves are uniting around the theme that the former head of Bain Capital looted companies, tossed people out of jobs and is now exaggerating his success at the venture capital firm.

In the context of this moment in American politics, in which frustration with the privileged is boiling hot, the attack, from Republicans on one side and the Obama campaign on the other, will test Romney. If he ends up looking more like an opportunist who profited for the few than like a man who created jobs for the many, it’s hard to imagine his polls numbers won’t drop.
