It’s a supremely tight race after Giuliani, but Rasmussen’s latest national poll has something of a shakeup, with Romney and Huckabee edging past McCain and Thompson.

“Giuliani attracts 23 percent support from Likely Republican Primary voters nationwide while Romney attracts 15 percent. Mike Huckabee is the top choice for 13 percent while Fred Thompson and John McCain each earn 12 percent support. Ron Paul’s is at 5 percent.”
