Mitt Romney's Team Questions Rick Santorum's Conservatism

The two leading candidates for the Republican presidential nomination -- Mitt Romney and Rick Santorum -- continue to fight over conservative credentials.

On Tuesday, the Romney camp took aim at Santorums record, insisting that conservatives cannot trust the former U.S. senator from Pennsylvania.

Fiscal conservatives are rightly appalled at Rick Santorums record on spending issues, said Ryan Williams, a spokesman for Romney. All too often, he was content to play the same old Washington games by taking one for the team instead of standing on principle. Republicans are looking for a proven leader who can take on Barack Obama and ultimately get our spending, debt and deficits under control.
