On the eve of Tuesday primaries in Michigan and Arizona, Mitt Romney and Rick Santorum appeared to be tied in the Great Lakes state though the former Massachusetts governor likely had the momentum and looked to be significantly ahead in the southwestern border state.
There was no shift over the weekend by Republican presidential candidate Rick Santorum when he was asked about his comment last year that then-presidential candidate John Kennedy's famous 1960 speech about religion and the separation of church and state makes him want to throw up.
GOP presidential candidate Mitt Romney plays up his Michigan roots when he talks to voters in the state where he grew up.
In 2008, Romney won the Republican presidential primary in Michigan. On the campaign trail, he likes to tell stories about his father, George, who was an iconic governor of Michigan in the 1960s:
"He said, 'It sure is great to be in Mount Clemens today,' even though he was in Mount Pleasant. My mother was sitting behind and said, 'George, it's "Pleasant." ' He said, 'Yes, it's pleasant in Mount Clemens.' "
When voters in Michigan go the polls Tuesday, it's unlikely many will tick the box for former House Speaker Newt Gingrich. In part, that's because Gingrich has all but written off the state, leaving his opponents to fight over it.
