DOVER, DE -- Given the opportunity to work in Mitt Romney’s cabinet, Newt Gingrich says he would pass.

Asked by a radio host inside a small diner whether he would work for a Romney administration if given the opportunity, Gingrich answered “probably not” but “not because I am opposed to Mitt.”

“Look, if the choice does end up being Romney versus Obama, I can be very, very enthusiastic for Romney, that is a huge choice. But I had a very good life doing a lot of fun things,” the former House speaker said. “I am very happy to be an adviser. I did a lot of that in the Bush administration both on health care and national security.”

Romney seems to have all but sealed the nomination – he still has not reached the 1,144 delegate count threshold – but Gingrich says he has more explaining to do.

“I’m making the case for a very ideas-oriented, solutions-oriented kind of conservatism, and I think Romney is going to have to explain a lot more of what he would actually do as president,” he said.

Gingrich also leveled sharp charges toward President Obama as well at the Hollywood Diner, where he was interviewed on Elliott in the Morning radio show.

“The thing that Obama does that’s fascinating is,” Gingrich said. “On one hand he has all the instincts of a Chicago machine politician. On the other hand he has all the fantasies of a good college faculty member.”

And the media was mixed in as well – an institution Gingrich claims is Obama’s “enabler.”

“The elite news media gets up every morning thinking how do we protect this guy because he’s so wonderful that even if he’s totally destructive he’s destructive in such a fun way that we really like keeping here there, and how do we protect him from himself, because after all it’s not his fault that he’s crippling the economy, bankrupting the nation, and doing a series of weird things, because we know he really means well,” he said.

Gingrich will continue to campaigning heavily in both Delaware, where voters take to the polls on April 24, and North Carolina, votes on May 8, because he believes wins there may get him back in the game – keeping alive the dream of debating Obama one-on-one this fall.
