Of course he wasn't, he knows how much of a nightmare Cain or Moore would be in the FED and how neither have anything remotely approaching even the current Republican parties fiscal goals.
They're happy to re-enact the Human Centipede with Trump, but only to a point. McConnell is more powerful than Trump and he knows it, which is why for example Trumps big health care push a month ago (earlier this month?) came and went in a matter of days with a thud. Because McConnell knew it was a losing issue and wouldn't touch it, because the Trump administration couldn't find another Senate Republican to lead their efforts (not even Rick Scott), and because the administration is completely incapable of taking the lead on any legislative efforts.
