The latest Rasmussen Reports telephone survey of South Carolina’s Republican Presidential Primary shows that John McCain and Mike Huckabee are tied at 24%. In a race that has already seen four different candidates with the lead, much could still change in the coming days--7% of voters have yet to make up their mind, 10% say there’s a good chance they could change their mind, and another 24% might change their mind.

Mitt Romney attracts 18% support and Fred Thompson 16%. Those figures are little changed from the previous survey. Both Romney and Thompson have led in South Carolina at some point over the past several months. The latest survey was conducted the night after Mitt Romney’s victory in Michigan. Ron Paul attracts 5% support and Rudy Giuliani 3%. Giuliani is betting his entire campaign on a strong showing in Florida, where he is now tied for the lead with three others.
