If he really has debt, he will be endorsing Mittler for a promise of retiring the debt. Romney made out quite well on endorsing McInsane last time. I think they handed him at least 35 million that he'd loaned to his own campaign. It may have been as much as 45 million.
If he doesn't really have debt, then he's angling for more money for a "think" tank. My guess, he'll call it the Campaign 4 Unliberty. And he can roll the funds raised under false pretenses into it, and give himself a handsome salary from it as well. Sounds about right.
