In FoxNews latest poll, John McCain leads with 27% and Mike Huckabee is trailing at 20% in South Carolina. But, almost 20% of the voters polled are still undecided, so, the outcome is still very much in play. Fred Thompson, who needs to win or at least a good showing is trailing with only 11%.

While Republican John McCain remains the front-runner in the South Carolina presidential primary, the outcome is up in the air as many voters are still considering their options, according to a FOX News poll released Friday.

Nearly one out of five likely Republican primary voters in South Carolina says they are unsure which candidate they will support on Saturday. Mitt Romney won the Michigan primary earlier in the week, while McCain won the New Hampshire primary and Mike Huckabee won in Iowa, leaving the Republican Party without a clear favorite.

The new FOX News poll shows McCain holds onto his lead in South Carolina by capturing the support of 27 percent followed by Huckabee at 20 percent and Romney in third with 15 percent. Fred Thompson, who was hoping to perform well in a state neighboring his home state of Tennessee, receives 11 percent, up just two points from earlier in the month.

This is becoming a 3 horse race pretty quickly with Rudy Guiliani and Fred Thompson fading. Guiliani is putting everything into winning in Florida, and Thompson is just not doing it. There is still time, but, it time is getting short.
