MARQUETTE, Mich. (AP) — The question of whether Mitt Romney is conservative enough to deserve the GOP presidential nomination is again taking center stage in the Republican contest.
Rick Santorum told Michigan voters Sunday that the former Massachusetts governor fails the test.
Santorum said Romney's record is virtually identical to President Barack Obama's on key issues, including mandated health coverage. He said the GOP needs a sharp contrast to Obama in November.
Romney said he is a solid conservative. He said he reduced taxes, enforced immigration laws, defended traditional marriage and opposed abortion in his four years as governor.
The Michigan and Arizona primaries are Tuesday.
