If he wins, he may be too busy to run an effective Presidential race. If he loses, he’ll have the time on his hands to start running early.
He and Palin are also friends so if she runs, he may take a back seat.
If he loses, it will MUCH harder for him to fundraise. Bush would not have been so formidable if he was handed his ass in his Texas gov re-election bid
Oh and if you happen to be really really rich, I heard the Jackson Ranch near Ft Hood but in Lampassas County is for sale around $37M or whatever. Its 9,300 acres and right nest to a state park. It’d be like a whole ‘nother country.
Future Galt’s Gulch maybe?
