Obama's tax plan will help GOP: Huckabee

If President Barack Obama continues to push his aim of taxing college savings plans, it will only send more votes to the Republican presidential candidate in 2016, former Arkansas Gov. Mike Huckabee , a possible presidential contender, told CNBC on Friday.

"If the president continues to want to tax people who have saved money for their kids' and grandkids' education, I think it will win the votes of anybody with an IQ above broccoli," Huckabee said in an interview with " Closing Bell ."

As part of his plan to help the middle class, the president has proposed taxing withdrawals from 529 college savings accounts. Right now, money can be withdrawn from those accounts tax-free if the proceeds are used for education.

Huckabee called Obama's approach irrational.

"To turn around and to say in addition to making it harder for working people to put aside money for their kids, we're going to turn around and redistribute and give free money to people who didn't save anything," he said, referring to the president's plan to make community college free for most students.

While Huckabee has said he will not decide whether to enter the race until late spring, he told CNBC he's leaning toward a run.

"I sure didn't leave my job at the Fox News network just because I wanted Saturdays off."

Huckabee, who was governor of Arkansas from 1996 to 2007, left his weekly Fox News program earlier this month and just released new book titled, "God, Guns, Grits, and Gravy."

He said that if he were to become president, he'd like to get rid of the Internal Revenue Service .

"I would love to see the fair tax, which is to rid ourselves of the IRS. I think it's a criminal enterprise," Huckabee said.

"When they use their power, which is an enormous power, to separate their investigations of people who agree with them and those who don't ... that is criminal."

The agency has been accused of targeting conservative groups, but has denied any wrongdoing.

Huckabee said he would also move to repeal Obamacare.

While he chose not to run for the White House in 2012, he briefly enjoyed front-runner status during the 2008 Republican primaries before dropping out of the race.

While Huckabee is a Baptist, he pointed out that religion has nothing to do with doing the job of president, and said he would support Mitt Romney , a Mormon, if he were to win the nomination.

"Even my own qualifications for being president have nothing to do with my being an evangelical, or a Baptist. It has to do with I was an effective and successful governor for 10 ½ years in the bluest state in America when I governed."

Former Florida Gov. Jeb Bush has also said he's considering pursuing a presidential bid, but the field of GOP contenders is expected to be wide and varied.
