He named popular GOP possibilities New Jersey Gov. Chris Christie, former Florida Gov. Jeb Bush, Rep. Paul Ryan (Wis.) and Indiana Gov. Mitch Daniels. All four chose not to run for the GOP nomination.
But with Rick Santorum and Romney neck and neck in the most recent Michigan polls before Election Day, King pointed out there is a real possibility Romney will lose in his home state.
“If Romney does not win Michigan it creates real problems for his candidacy,” King said. “And Rick Santorum has had a lot of negatives over the last week. If he is still able to win Michigan, that shows a real problem that Mitt Romney has."
King echoed many other Republicans who have suggested the long primary process makes Republicans weaker heading into the general election.
“I think there’s going to be more of an interest, more of an emphasis, of having someone ready on Super Tuesday if Mitt Romney does not manage to break loose,” he said.
“I think they'll be getting lined up, they’re getting recruited,” King continued. “And they’re trying to get one of them to agree to make the run, let’s say, if Super Tuesday doesn’t turn out better for Romney.”
