 He's in the clown car again!

   Washington (CNN) Mike Huckabee's announcement on Saturday to end his Fox News show marked yet another significant move by a key player in the race for the Republican presidential nomination, bringing the 2016 contest further into focus as a deep bench of prospective candidates begins to test the waters.

   The former Arkansas governor said Saturday night's episode of "Huckabee" would be his last. It was a necessary step, he said, as he explores a second presidential bid, a decision he stressed he won't finalize until the spring.

   "I say goodbye, but as we say in television, stay tuned. There's more to come," he said at the end of his show.
