Mitt Romney has moved ahead of Rick Santorum in the Michigan and Arizona polls but Santorum is campaigning hard as voters turn out for primaries in both states, Tuesday, Feb. 28.

The former Massachusetts governor was behind last week but has surged on the strength of his performance in the televised national debate in Arizona last Thursday.

According to an average of four Sunday polls compiled by RealClearPolitics, Romney leads 37.3 percent to Santorum at 35.8 percent. Only one of those polls, the Mitchell/Rosetta Stone, had Santorum ahead, but that was marginal at two points.

Speaking in Albion, Mich., Romney was upbeat telling supporters, “This sure has been fun these last 10 days or so. We started out about 15 points down in the polls. Now we’re leading in the polls,” he said.
