Well, every President has people either leave and/or be replaced; Obama had 2 different Secretaries of State (Clinton, Kerry), and 2 different AG's (Holder (who was held in contempt of Congress no less), and Lynch)... and there are other Adminstration officials, including at least a few who left because of legal/corruption/ethics issues..... There is no 'scandal-free' Administration, and Obama's was no exception (of course, fake newsies of the MSNBCNN-WaPo-NYT Axis will try to dupe you otherwise).
** BUT, it IS true that Trump has had significant problems with 'Swampers' or members of the so-called 'Deep State' that have PURPOSELY came in to cause issues...
** AND, there have been a whole lot of them who have been holdovers from Obama, who most certainly were there to cause problems (that's part of the whole 'Resistance' thing that you've talked about before, remember?)
** HOWEVER, in any case, Trump really should have tried better at weeding out these assholes, or preventing new ones from coming-on or old ones moving-up....
** ON THE OTHER HAND, the Swampy, Deep-State nature of many in the Republican Party, were/are there to falsely advise and further cause trouble....
* All of this shows that the Deep-State and Swamp DO certainly exist, and they are a force to reckon with; they think that they own the Country, and many, many suckers out in the Public are only too glad to give it away to them (do you know anyone like that?)....
* Very early, the corruptocrats worked to 'take-out' Jeff Sessions, and Michael Flynn, either by frame-up, or resignation or by putting him 'in-a-box' (which is what they did to Sessions); this allowed the pieces-of-shit, like Comey and McCabe and many subordinates (or insubordinates) to purposesly create fuster-clucks.....
