The Committee to Stop Mike Huckabee

Mitt Romney, eyeing a challenge to President Obama in 2012, is endorsing John McCain.

Meanwhile, Mike Huckabee is scheduling a speech in the Cayman Islands.

Huckabee will be there Friday night through Sunday morning and be back in Wisconsin Sunday evening to campaign through Tuesday when they hold their primary.

But when he returns to Wisconsin he will have $400 million worth of ads.
