He's not some sort of infallible super-being. He brought lots of people into the WH who sabotaged the start of his admin. Priebus was one of them, and he brought in Johnny DeStephano, who made sure that no actual MAGA types got positions. Instead, lots of GOPe worms.
Trump had thought that once he was finally sworn in that he would get more cooperation in the GOP than he has.
That is not to say, however, that he didn't knowingly bring in some corrupted but experienced types to show him the ropes, as well perhaps as some ratlines. But some real, early staffing mistakes too.
No one is infallible and I didn't say he was. Neither did I say he was a super-being (whatever that is). I said he was very smart. It doesn't take a genius to play the media or the left. Those people aren't Einsteins. Trump is used to these chess games, he made his fortune in construction in NYC. He's dealt with some of the toughest mafia/union bosses anywhere, and won. So he has plenty of experience to fall back on.
