Huckabee, who has admitted he doesn’t know what he’s talking about, criticized Bush’s foreign policy. He sounds just like the left:

Mike Huckabee, who has joked about his lack of foreign policy experience, is criticizing the Bush administration’s efforts, denouncing a go-it-alone “arrogant bunker mentality” and questioning decisions on Iraq.
Huckabee, the former Arkansas governor now running for the Republican presidential nomination, lays out a policy plan that is long on optimism but short on details in the January-February issue of the journal Foreign Affairs, which is published by the Council on Foreign Relations. A copy of his article was released Friday.
“American foreign policy needs to change its tone and attitude, open up, and reach out,” Huckabee said. “The Bush administration’s arrogant bunker mentality has been counterproductive at home and abroad. My administration will recognize that the United States’ main fight today does not pit us against the world but pits the world against the terrorists.”
In one specific criticism, Huckabee said Bush did not send enough troops to invade Iraq. And he accused the president of marginalizing Gen. Eric Shinseki, the Army chief of staff, who said at the outset of the war that it might take several hundred thousand U.S. troops to control Iraq after the invasion. “I would have met with Shinseki privately and carefully weighed his advice,” Huckabee said.

Separately, Huckabee also named Republican political strategist Ed Rollins as his national campaign chairman. Rollins was national campaign director for Ronald Reagan in the 1984 presidential election.

Romney had the same take:

Mitt Romney accused Republican presidential rival Mike Huckabee of “running from the wrong party” for criticizing President Bush’s foreign policy as an “arrogant bunker mentality.”
Romney defended Bush against Huckabee’s charge, which the former Arkansas governor leveled in the January-February issue of the respected journal Foreign Affairs.
“I can’t believe he’d say that,” Romney said to a gathering of about 100 supporters in a restaurant here. “I had to look again-did this come from Barack Obama or from Hillary Clinton? Did it come from John Edwards? No, it was Governor Huckabee.”

It’s clear to me that Huckabee is the most anti-Reagan candidate in the pack.
