AP via WRAL says that Mitt Romney is pulling advertising out of South Carolina, “a sign of trouble for a campaign that badly needs a win.”

“We feel the best strategy is to focus our paid messaging in Michigan,” Romney spokesman Kevin Madden said Wednesday. …

Romney had been spending about $280,000 per week in South Carolina and spent $3 million there last year, according to rival campaigns. …

The state still looks up for grabs to me. I know this, I’ve been back and forth through much of South Carolina on business the past year and the Romney signs were out all along the Interstate w-a-y early. They were worse than the viral Ron Paul promotions around here.
