No, Trump's problem was he came from industry where he could hire anybody, give them a chance, and if they turned out to be idiots then fire them on the spot.

In politics you have to vet people years before they even get to your desk because they can't be fired. You need a network of trusted people to do that, and you need to know their embarrassing or compromising information so that nobody else can use them against you.

Trump could have been successful if he had a trusted VP, but Pence was either a snake or Trump didn't trust him.
