Insider Advantage has a new poll out in South Carolina on the Republican primary:

Republicans
Giuliani 18
McCain 17
Gingrich 17
F. Thompson 13
Romney 8
Huckabee 6
Hunter 3
Brownback 3
Gilmore 1
Paul 1
Undecided 13

Without wanting to put too much stock in any one poll, it's probably worth pointing out that while Romney has definitely been on an upward trajectory in Iowa and New Hampshire, he ticked down in this poll and overall his support in South Carolina has remained consistently - and somewhat surprisingly - soft. This is the first post-debate, post-immigration reform brouhaha survey taken in South Carolina, so we'll have to wait and see what, if anything, we can learn from the arrival of more poll data.

McCain leads by 5.0% in the freshly updated RCP Average for South Carolina.
