The Republican (as in Republic) case against JEB! in 2016 is a simple one

It seems safe to say that JEB!, while he may be the 2016 Republican nominee, will never be president. That bit of wishful thinking is premised on a couple of assumptions.  One, that the American voter will not elect another Bush in 2016 because of the records of the last two Bush presidents, particularly the last one, and two, that the American voter is dedicated to preserving a constitutional republican form of government. It is this latter assumption, ironically, that probably is not the one that will doom JEB!  But it should.   It is also an irony that a party going by the name Republican, if it nominates a third member of the same nuclear family within one generation for the presidential office would itself be the greatest threat to the Republic.The case against JEB! is as simple as that.  It does not matter what he believes, how well educated he might be, how "smart" (or "smarter" than his two familial predecessors) he may be, how "compassionate" he may be, or pretend to be, or how much he wants to "serve. " None of that matters.   There are plenty of people, not in his family, who are smarter and more capable of serving as president than the Crown Prince, and whether or not he meets a minimum level of competence for the office is irrelevant.

His advocates are already, and will ramp up their defense of his pretense to the White House with an argument that he should be evaluated on his on merits, and that his father and brother are irrelevant. They are wrong.  What matters, for our constitutional republic, is that his brother and his father were both presidents, and he should not be for that reason alone.  That is all that matters.  

It is also problematic that the wife of a former president will be the opponent of this man whose brother and father have held the office, but if JEB! manages to buy, or somehow obtain the presidential office in 2016 by virtue of familial, oligarchic or plutocratic connections, and with Bush family sycophants Boehner and McConnell in charge of the House and Senate, the United States will become an effective American Principate, from which there is likely no return.
