Former Gov. Mike Huckabee (R-Ark.) isn't ruling out a run for the White House in 2016, despite opting out of a bid in 2012.

"You never rule anything out for the long term," Huckabee said on an Israeli political talk show. "I'm not making an announcement, but certainly when people say, 'Would you ever do it,' I very might well do that."

Huckabee publicly considered running for president in 2012, but opted out, saying his heart was telling him not to.

"It just wasn't the right time for me," he said Friday. "Maybe someday it will be the right time."

While in Israel in 2011, Huckabee told The Hill that the vast amount of money it took to run a viable modern presidential campaign was a disincentive, but that he had broad support among Republicans, including in centrist states such as New Jersey and Pennsylvania.

Huckabee ran for the GOP nomination in 2008 and won the Iowa caucuses, but dropped out after a string of wins by eventual nominee Sen.

Huckabee is in Israel leading a group of visitors on a Christian-themed tour. He said last week while on the trip that Republicans couldn't decide what they wanted from their presidential candidates, and that none of the candidates had impressed him sufficiently to earn his endorsement.
