I agree that Democrats are in the Executive Branch specifically to undermine POTUS, but the Civil Service rules may be a problem for him.
It is very difficult to fire GS workers below the GS-16 level.
You will note that EVERY Republican President since WW II has had that problem - the Democrats “burrow in” and stay behind to bedevil succeeding Republican Presidents.
For at least two reasons, Republicans do not stick around when a Democrat wins the White House: 1)Republicans do not like working for Democrats, and 2) Republicans do not “burrow in” to sabotage Democrat Presidents like Democrats do.
President Trump has managed to rid himself of a lot of “leakers” and Democrat AND Republican “Never Trumpers,” but he still must deal with them.
I am confident that he will prevail! And we all must hope so!
