GOP Rivals Pounce On Romney 'Etch A Sketch' Controversy

Mitt Romney is once again facing criticism from Republican rivals that he is not a true conservative. This time for comments that his campaign guru, Eric Fehrnstrom, made on CNN.

When asked if Romney had moved too far to the right for the general election, Fehrnstrom said the fall was basically a do-over.

"It's almost like an Etch A Sketch," he said. "You can kind of shake it up and we start all over again."

In Louisiana, Rick Santorum brandished an Etch A Sketch and told voters he is a candidate who stands "firmly on the rocks of freedom, not on the sands of an Etch A Sketch toy."

Newt Gingrich stood on stage elsewhere in the state and explained to his audience just what the toys were.

"Gov. Romney's staff, they don't even have the decency to wait until they get the nomination to explain to us how they'll sell us out," he said. "I think having an Etch A Sketch as your campaign model raises every doubt about where we're going."

Louisiana holds its primary Saturday. Santorum is favored in the state, though Romney's allies are airing TV ads there even though the South has proven less hospitable to Romney.

Beyond Saturday, polls show Romney has the advantage heading toward Maryland's April 3 primary.
