Rand Paul isn't mentioned by name, but in NYT Alec MacGillis provides us with a behind the scenes glimpse at Mitch's real views:
Sometimes, Mr. McConnell could use this right wing to his benefit — warning the White House, for instance, that it had better accede to Republican demands on the debt ceiling in 2011 lest the renegades take the country to default.-RW
More often, though, these self-described revolutionaries confounded him, which led to explosions of frustration like the one that a longtime associate witnessed in 2011: “He said, ‘Those idiots, those people come up here and have never been in office and know nothing about being in office.’ ”
Such outbursts were kept under wraps, of course. Mr. McConnell needed to appease enough of the chaos makers in order to stay atop the Republican caucus, and to overcome a Tea Party Republican challenger leading up to his 2014 re-election.
