Lots that he’s presumably compromised on. The issue of likely illegal adoptions of his children, his being understood to be a closeted homosexual, his showing up in Malta likely to receive a payoff for an overseas account when he first went unconstitutional with Obamacare, to his reported Knights of Malta sworn fealty to the Queen.
Then of course there is the simple fact of almost everyone in DC being compromised, that he was named by a Deep State Bush, and the unfortunate example of Scalia seared into the minds of all the Justices.
But who cares? His children are all adults and have been for many years now, he’d probably be a hero if he turned out to be gay, and as for Malta, I think he may be a member of the Knights of Malta, a Catholic organization, and I doubt that he needed a payoff for Obamacare.
He just wanted to look “fair” and “non-partisan” and get the praise of his enemies. You underestimate the power of a weak man’s ego.
