Mike Huckabee, the former governor of the U.S. state of Arkansas, said today he won't launch a second campaign for the Republican presidential nomination.
Huckabee, the Republican winner of the crucial Iowa caucuses in 2008, announced his decision on Fox News.
Huckabee's decision further muddies the Republican field as the Republican Party seeks a challenger for President Barack Obama, whose approval ratings have risen since the killing of Osama bin Laden.
Huckabee, a prominent social conservative, ranks high in national popularity polls.
