WASHINGTON — Some of Mitt Romney's rivals are waging an attack on him you'd never think would come from Republicans who claim Ronald Reagan as their hero. They're blasting the GOP front-runner for aggressive, wealth-creating business tactics.

The attacks, from former House Speaker Newt Gingrich, Texas Gov. Rick Perry and former Utah Gov. Jon Huntsman, didn't seem to matter much in New Hampshire. Romney claimed a comfortable primary victory there. Huntsman came in a distant third, Gingrich was fourth and Perry was sixth.

But the criticism may have more resonance in next-in-line South Carolina and in Florida. Both states are struggling with high joblessness and weak housing markets. South Carolina's primary is Jan. 21, Florida's is Jan. 31.
