Fatal flaw of Trump was NEVER draining the swamp and actually filling it. He accomplished great things alone but never had a chance never having the opportunity to work with a strong and stable administration and GOP collectively.
I think in the end Trump opened the door a bit.
The problem was always to find people who wanted to work for him, and take the arrows that came with it.
And considering those were people who were already doing well in the private sector, why would you have expected them to give it up for that?
So basically Trump was stuck with the same old DC Lifers, and he could only appoint those Mitch told him he would approve.
The story may very well be in the end, that Trump paved the way for someone else down the road to carry on the MAGA task.
Would there have been Reagan without Goldwater?
