Supporting Mike Huckabee's presidential campaign is no longer a family affair for the Hutchinson clan. Former congressman Asa Hutchinson said Thursday he's no longer backing Huckabee's presidential campaign and he endorsed presumptive GOP nominee John McCain. Hutchinson's brother, former U.S. Senator Tim Hutchinson, is a top Huckabee supporter.The Hutchinson family has had split loyalties in the presidential race. Tim Hutchinson has been one of Huckabee's most outspoken supporters, while his ex-wife, state Representative Donna Hutchinson, campaigned for rival Mitt Romney while Romney was still in the race. Tim Hutchinson's son, Jeremy, had backed Fred Thompson's unsuccessful bid for the Republican nomination before the Tennessee senator dropped out of the race. Asa Hutchinson says, "I would say that the discussions at Hutchinson family events are always interesting."
