On his radio show Friday, conservative talk-show host Glenn Beck ripped former Arkansas Gov. Mike Huckabee over his stance on taxes, immigration, pardons and first lady Michelle Obama's anti-obesity program.

"There are political issues that would allow me to not vote for Mike Huckabee. He's a big-government guy," Beck said.

The comments were part of an ongoing feud between Beck and Huckabee, who has not announced whether he'll run for president again in 2012.

Beck had criticized Huckabee previously for supporting the first lady's "Let's Move" initiative.

Huckabee, who lost more than 100 pounds prior to his 2008 campaign and has struggled with obesity, fired back with: "Why Beck has decided to aim his overloaded guns on me is beyond me. But he ought to clean his gun and point it more carefully lest it blow up in his face like it did this time."
