Iowa Poll: Romney Leads, Cain Surges

Public Policy Polling reports:

Mitt Romney has the lead in PPP's first Iowa poll since Mike Huckabee and Donald Trump exited the race, but with six different candidates polling in double digits it's clear this thing is wide open.

Romney polls at 21%. Sarah Palin and Herman Cain are tied for second at 15%. Newt Gingrich is 4th with 12%, Michele Bachmann 5th with 11%, Tim Pawlenty 6th with 10%, Ron Paul 7th with 8%, and Jon Huntsman 8th with 0% (only one respondent to the poll picked him.) 8% said they supported someone else or were undecided.

Cain and Palin have been the biggest beneficiaries in Iowa of Huckabee and Trump's decisions not to run. Cain is at 15% now despite not even having been included on our last poll. Palin's gained 7 points in the six weeks since our last poll compared to 5 point gains for Romney, Pawlenty, and Bachmann, a 3 point gain for Gingrich, and a 2 point bump for Paul.

Romney's leading in Iowa based on his strength with centrist and center right Republican voters. With moderates he's at 34% to 16% for Palin, 13% for Paul, and 11% for Gingrich. With 'somewhat conservative' voters he's at 24% to 15% for Pawlenty, 13% for Palin, and 12% for Gingrich and Cain. His strength with those two groups outweighs his continuing weakness with the furthest right group of voters in the state, which constitute the largest segment of the Republican electorate at 41%. With those 'very conservative' folks Romney can muster only a fourth place finish at 13%. Cain and Palin tie for the lead with that group of voters at 19% followed by Bachmann at 15%.
