Poll watch: Romney cruising in Arizona; it’s a mixed-bag in Michigan; Santo up in Ohio


With less than 24 hours before the Arizona and Michigan primaries, here’s the latest polling information:

A new Public Policy Polling survey in Arizona shows Mitt Romney is headed for an overwhelming victory in Arizona’s primary on Tuesday. He leads Rick Santorum, 43% to 26%, with Newt Gingrich at 18% and Ron Paul at 11%.

Key finding: “Almost half of those planning to vote have already cast their ballots, and Romney has a 48-25 advantage over Santorum with those folks. That lead makes it nearly impossible for Santorum to make up the difference on election day, and Romney has a 39-27 advantage with those planning to vote on Tuesday anyway.”

A new We Ask America poll shows Romney leading Santorum, 43% to 27%.

Though a Public Policy Polling survey released late last night showed Romney regaining the lead over Santorum in the Michigan GOP primary, 39% to 37%, a new Mitchell Research/Rosetta Stone poll shows Santorum taking over the lead back from Romney, 37% to 35%.

A final We Ask America poll shows Romney ahead 37% to 33%.

Meanwhile, A new Quinnipiac poll in Ohio shows Santorum leading the GOP presidential field with 36% of likely Republican primary voters, followed by Romney at 29%, Newt Gingrich at 17% and Ron Paul at 11%.

Said pollster Peter Brown: “A week out, Sen. Rick Santorum remains seven points ahead among Ohio’s likely Republican primary voters. While almost half the voters say they might change their mind, Santorum supporters seem a little surer of their vote. What happens in Michigan tomorrow night might have an impact on voters in Ohio’s Republican primary.”
