I think you have to be crazy to want the job. I think they’re all bat-shit crazy.
No, most are just venal and power mad like the Obamas and Clintons. Some just think they can do a better job that anyone else available, like Trump. That may be unrealistic ego, but he is 69 and just making money doing the same kinds of projects over and over again must lose its appeal at some point. He has been Monday-morning Quarterbacking politics for decades. Time to put up or shut up, and Donald doesn’t “shut up” worth a damn.
On the face of it, stepping away from an enterprise that is earning you $400M/yr for a 24/7 job with low pay and lots of aggravation seems pretty crazy.
His record is one of not backing down from a challenge, and instead volunteering for challenges, and he has generally succeeded. I kind of think he didn’t expect to get this far but has now found himself “drafted” by the voters and sees it as a challenge he owes America to win.
