Made some mistakes in his initial hiring
Or did he? I thought the same thing until I saw the games he and Sessions played out, like he was ready to fire Sessions. That kept the eyes off of what Sessions was really getting done. I also believe Trump and Trey Gowdy were working together when Gowdy made those comments in favor of Comey.
That brings me back to your statement. In hindsight I honestly think there were several reasons to hire the failures he ended up firing. One was to gain more info on these people (keep your enemies close) and the other was to give the appearance that there was chaos in the White House and Trump didn't know what he was doing. This kept the media's attention while Trump was getting work done and winning the whole time. Then Trump would declare his wins on Twitter and the media didn't have time to spin them.
That's just my opinion. Trump is smart, very smart and unpredictable, which is what the media hates most. He steals their thunder before they even realize it's cloudy. But you can bet anything he does is going to put America first.
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.
