Palin has exponentially more draw with the base than does Jindal.
Jindal whilst conservative is sorta lackluster and I think his main draw for many here is his uniqueness which I think is the wrong path for conservatives.
Identity picks.
Palin inspires folks and scares the hell out of the left.
Haley Barbour speaks much better and very disarming and affable but quite potent and is just as conservative but he’s a chunky late middle aged white guy with a southern accent.
Why not him instead of Jindal.
As for Haley, he's a good old boy. He's a good debater. Not sure if he has the type of salesmanship skills/gifts I'd like to see in a presidential pick. But then, neither did McCain. Neither did GWB. Neither did Bob Dole. Neither did Bush1. The GOP looks rather pathetic.
