GOP strategist Nicole Wallace on Sunday said that it was not a problem that Republican nominee Mitt Romney was "like an alien that ripped off his mask" when he seemed to change positions during the presidential debates because "we liked him better."

During an ABC News panel on Sunday, The Daily Beast's Andrew Sullivan noted that Romney had presented himself as a "brand new candidate" at the debates.

"The Mitt Romney that showed up on Oct. 3 was like an alien that ripped off his mask and said, 'I'm brand new now,'" Sullivan pointed out.

"But we liked him!" Wallace exclaimed. "Isn't that the point? But we liked him better!"

"He has evolutionary ideology like the church has revolving doctrine," Sullivan continued. "One day it's true, the last day it's not."

Wallace argued that President Barack Obama was "eroding his own trust and credibility" by attacking Romney for constantly changing positions.

"You cannot be wrong and coreless," she said. "So, I think Obama had undermined his own attack by not being able to settle on one."

"I'm sorry, but Romney was a severe conservative from January to October," Sullivan countered. "And now he's a new candidate. What I'm amazed at is why Republicans aren't scared about what he'll be in January or July next year."

"Because what ever it is, is better than Obama," Wallace opined.

"How do you know that?" Sullivan shot back. "Because he's supporting what will be a massive increase in debt. His math will balloon the debt just like President [George W.] Bush did. Tax cuts, increasing in spending and no details -- increase in defense spending -- and no details about how to balance the budget?"
