I heartily agree with the core of your assertion, to wit: “John McCain should not have been the GOP candidate.”
RE: “John McCain should not have been the GOP candidate.”
Let’s put it this way, IF the requirement that he be BORN IN US SOIL is part of the definition of “NATURAL BORN”, he could be the most perfect candidate, with track record and policies that satisfy every true conservative, yet, HE WOULD NOT BE ELIGIBLE to be President regardless of which party embraces him.
