Rick Santorum and Mitt Romney competed over conservative credentials and faced tough questions from voters in Arizona and Michigan on Tuesday.

The battle for the Republican presidential nomination heads into a potentially decisive phase over the next two weeks with contests in 13 states that could finally answer some of the questions that have defined the race.

A political group supporting Mitt Romney’s Republican presidential bid began airing television advertisements in Michigan today, charging that rival Rick Santorum is a “big spender” and “Washington insider” who backed letting convicted felons vote.
