I don't get why so many Republicans are putting all their chips on a 74 year old person in poor health (or at least seems like he is in poor health and his actual health records are a guarded secret) facing a real threat of financial ruin and/or criminal prosecution, who is despised by many, if not most, Americans.
I mean, even if you like the guy, surely they would see that he comes with certain serious liabilities that would make him a less-than-ideal pick for building a viable political party.
