Former Gov. Mike Huckabee

Former Arkansas Gov. Mike Huckabee is once again panning the possibility of former Massachusetts Gov. Mitt Romney as John McCain's running mate, saying it eliminates what he calls "the Joe Biden issue" for Republicans.

"During the primary, Romney attacked McCain. He attacked me," the one-time presidential hopeful said today on Rush Limbaugh's radio show. "One of the problems McCain would have if he picked Romney was that it takes the Joe Biden issue off the table where Biden is saying great things about McCain and terrible things about Obama. They'll be running those tapes back over and over during the debates when Romney was attacking McCain and saying, 'Which time do we trust you? Then or now?'"

Limbaugh responded he didn't think the primary infighting among Republicans would make much of a difference in the general election.

"That's true for both parties, and McCain's running ads right now featuring Hillary endorsing him," Limbaugh said. "There is a gold mine of Hillary audio and video that McCain can make an ad of. Those things happen in primaries."

Huckabee said he would still support McCain even if Romney is selected as running mate, citing his opposition to abortion rights.

"My attitude is John McCain is pro-life" said Huckabee. "He's clear about that, and I'm gonna support him because he's certainly got a much clearer understanding of when life begins than Barack Obama who after 47 years of life says it's above his pay grade."

He also took a stab at Democrats who trust scientists when it comes to alleged global warming but not when human male and female chromosomes join together at conception.

"That's not only a life, but it's a human life. It's not a stalk of broccoli, it's not a golden retriever. It's a human life and that's irrefutable science," said Huckabee.

Huckabee also is hoping McCain does not choose pro-choice Sen. Joe Lieberman as his running mate.

"Lieberman would be a disaster from my perspective because Republicans want to elect a Republican," he said.

"How would you have a debate between Lieberman and Biden when they essentially would sit down there and drink a cup of coffee and agree with each other during the vice presidential debate? And you've got to have somebody that when that person goes up against Joe Biden, takes it to him and can go right to his face and put a little elbow in there underneath the basket."

Huckabee also questioned Democratic candidate Barack Obama's choice of Biden to be his running mate, instead of former first lady Hillary Clinton.

"I was surprised by the Biden pick in a way," he said. "That to me was like going to Baskin-Robbins and picking vanilla. I could not understand what he was thinking and I think the polls are now reflecting that it shows a lack of judgment and capacity to think about the playing field out there."

Before his departure, Huckabee was asked how Republicans would respond if New Orleans is threatened by a potentially strong Hurricane Gustav during the GOP convention.

"I think they've called in [televangelist] Pat Robertson to pray it off the coast," Huckabee joked.
