Romney's victory speech Tuesday stood in stark contrast to one he gave one week earlier in Iowa, where he delivered an impassive version of his stump speech after winning the state caucuses by just eight votes.
"Americans know that our future is brighter and better than these troubles times," Romney said, as applause and cheers briefly interrupted him. "The president has run out of ideas. Now he's running out of excuses. And tonight, we're asking the good people of South Carolina to join the good citizens of New Hampshire and make 2012 the year he runs out of time."
"Tonight, we made history," Romney said. "Tonight we celebrate, tomorrow we go back to work."
