DES MOINES, Iowa — Prior Iowa caucus winner Mike Huckabee is reacquainting himself with activists who could help decide the next Republican nominee.

Huckabee appeared before the Iowa Freedom Summit on Saturday to deliver a biting assessment of President Barack Obama’s policies and make a pitch for his potential candidacy. He recently left a cable news show and is on a book tour.

The former Arkansas governor mocked Obama’s elevation of climate change as a critical issue. Huckabee says a greater threat is violent radical elements stoking fear around the world. He says America hasn’t done enough to strike those terror groups.

Huckabee also says Democrats are misguided by focusing on raising the minimum wage instead of cultivating better-paying jobs.

Huckabee has re-emerged as a possible presidential candidate seven years after his last bid.
