The sooner Huckabee is a candidate, the sooner he has to give up his lucrative TV career. Huckabee could arguably get in as late as a year from now (or later?) and immediately jump to the head of the pack in Iowa polls. What Palin does affects Huckabee's chances. Why not wait to see if she runs and/or if she implodes? And why not wait another 8 months to get a closer view on how Obama's chances might look in late 2012?
