In 2011, Mitch Daniels seemed too henpecked by his Diva wife to declare his candidacy. Better ask the Missus first if she would ‘let him’ run.
Sort of... He did not run, and it was because of her, but it is because he didn't want her to relive her humiliation. She abandoned him, and their young daughters, to go play with her lover in CA for a few years. She eventually woke up, and he took her back.... but she didn't want that to be thrown in her face during the campaign (as we all know the MSM would do), and he once again deferred to what was best for his family. Some might call that a weak husband, others might think higher of him for it.
Mitch is very very good fiscally, and should be considered for other posts that get less limelight.
