He will never be ready.
There will be no time whatsoever for a learning curve in Washington...none....and he will most defiantly need that time.....Further he's just not where he needs to be to handle the International Climate... Walkers foreign policy experience is ‘very’ minimal....which he's already shown weakness of in his speeches.
He may have done well in his state...which is pretty easy to do when it's in bad shape to begin with...but he's not near ready for a Presidential position IMO.
