Governor Chris Christie calls Mitt Romney's loss in the South Carolina "clearly disappointing" but calls winner Newt Gingrich “an embarrassment to the party" during an appearance on NBC's Meet The Press on Sunday.

Making his 3rd appearance in a week on an NBC program, Christie calls Gingrich's ethics violations and his losing the House speakership as a "prologue" to what could happen if the Georgian Republican wins the Oval Office according to Poltico.

"I mean he was run out of the speakership by his own party, he was fined $300,000 for ethics violations. This is a guy that has had a very difficult political career at times, and has been an embarrassment to the party," said Christie. "What the country needs, the governor said, is not “another legislator in the Oval Office who doesn’t know how to use executive authority.”

Christie admits that the Romney campaign had a "bad week" but predicted a rebound in the Florida primary on January 31.  “You know, I’m not going to try to say last night was good news for the Romney campaign. We had a bad week as a campaign, and a bad result last night," Christie said. "So, you pick yourself up, dust yourself off and you get to Florida and fight. I still believe that Governor Romney’s going to win in Florida on the 31st, and then return to Florida in August as the Republican nominee.”

Governor Christie will be in the Townsquare Media New Jersey studio with Eric  Scott for the month's Ask The Governor on Tuesday, January 31.

Christie continued to take aim, scoffing at Gingrich's title of strategic adviser. "That is the oldest Washington dodge in the book. That's because he didn't want to register as a lobbyist,” Christie said.

“First, he said he was a historian and now a strategic adviser. It's the oldest dodge in the book," he added. "He was using his influence he obtained in public office to help them. That's why they paid him $1.6 million. He can call it whatever he wants to call it, but that's what it is. Every candidate will have liabilities. What I was saying to Oprah in that interview, it's a challenge for Governor Romney and as campaigns evolve, people meet those challenges. I believe Mitt Romney will meet that challenge and connect."

Christie also answered again the question of being asked to be Vice President. “If I'm approached I will listen, but my inclination, I want to make it very clear, is that I want to stay governor of New Jersey."

David Gregory brought up Christie's proposed 10% income tax reduction asking how the state could afford the tax cut, noting that Christie scrapped a planned New Jersey-to-Manhattan rail tunnel in 2010 because the state was "broke" and couldn't afford to pay its share of the $8.7 billion project.

Noting the large budget deficits he's faced in the past two years, Christie said he was able to deliver balanced budgets --without tax increases -- through "very difficult, aggressive" spending cuts.

And since his plan will be phased in over three years, the governor says it won't be a budget buster.
