Nothing in the above has any dose of reality to it.
John McCain is not a “conservative Republican.” Hillary does not have “integrity.” Hillary does not have “all of the qualities that are necessary” to be president. Hillary does not have “a very different philosophical view.”
John McCain is has some idiotic thinking if he said or believes those things. They are all very provably wrong.
I’d certainly agree with Hillary having “a very different philosophical view”. (Whether it is particularly different from John McCains view is another matter). As for the rest, perhaps he knows something we don’t. Maybe Hillary really likes puppies, donates loads of money anonymously to various good causes, and weeps real tears without recourse to onions. Who can say? Sounds a tad unlikely though.
