This is a pretty good article with the historical context, but it ends “You’re a Bush. You’re supposed to be the candidate of the much-maligned, level-headed establishment. It’s time to start acting like it.”
What this author and most others fail to grasp is that the current movement and support for Trump (I disagree with his opinions as to why Trump is doing so well) is ANTI-ESTABLISHMENT. Jeb is thoroughly identified with the GOP Establishment & the status quo - i.e. bowing to Obama & being outwitted by the Dems on everything & he perfectly reflects their weakness, lack or will, cronyism and being out of touch with ‘we the people’. These behaviors & characteristics won’t “play” any more with a good segment of the Repub voting population. Jeb can hang around and hope for Trump to implode or go up in flames and it still won’t help him. He is primarily same ‘ol, same ‘ol and to further make his prospects worse, he is blah, low energy (thank you Trump for that description), dynastic (we are not a monarchy), and he absolutely will not take the dramatic, bold steps necessary to reverse the lawless, bold, America-wrecking actions that Obama has taken. Jeb can also show his “love” for illegal aliens in his personal life, but AMERICANS, not “bi-culturals” want borders, which to be effective, will not be ‘loving’. If Jeb is the Repub nominee by hook or crook, it will be the last nail in the coffin for the GOP, IMO.
What you wrote is common sense to me and everyone else outside the beltway and in teacher’s lounges (so, I guess it is actually uncommon sense). To me, that is the biggest value of Trump’s run...he has basically smoked out all the liberal elites who have been hiding behind the R.
