Raleigh, N.C. – The Republican caucus in Iowa is headed for a photo finish, with the three leading contenders all within two points of each other. Ron Paul is at 20%, Mitt Romney at 19%, and Rick Santorum at 18%. Rounding out the field are Newt Gingrich at 14%, Rick Perry at 10%, Michele Bachmann at 8%, Jon Huntsman at 4%, and Buddy Roemer at 2%.
The momentum in the race is completely on Santorum's side. He's moved up 8 points since a PPP poll earlier in the week, while no one else has seen more than a one point gain in their support. Among voters who say they decided who to vote for in the last seven days he leads Romney 29-17 with Paul and Gingrich both at 13. Santorum's net favorability of 60/30 makes him easily the most popular candidate in the field. No one else's favorability exceeds 52%. He may also have more room to grow in the final 48 hours of the campaign than the other front runners: 14% of voters say he's their second choice to 11% for Romney and only 8% for Paul.
