First, I knew Jeb was unworthy because of letting Terri Schiavo die such a horrific death. Then, I knew he was unlikeable when the campaign first started. Third, I knew he was not his own man because whatever he said or did on his own was mind-boggingly dumb. Final stage I knew he was delusional when there was a report that he'd made an ad in which he treated what happened to Teri Schiavo as a positive.
The silver lining is that with GWBs administration under scrutiny and the new book Jeb! and the Bush Crime Family, the whole dynasty's image has been destroyed by Jeb's ill-conceived candidacy.
