District Courts have Senior Judges who are "semi-retired" except they really aren't. If they wish to, they can still keep handling cases full-time or part-time, either way they are still fully involved regardless of being "semi-retired" Essentially this means many District Courts are filled with DS Senior Judges who can still cause a lot of damage even if the President fills Vacant District Judge seats. However there is one catch here: They don't occupy their seats which means the President can at any point replace them with full-time District Judges.

Mitch Mcconnell has already been asking Senior republican Judges to step down voluntarily so their seats can be replaced. He is only doing this out of respect for them so that they avoid humiliation and the President don't have to forcefully replace them(which he can do at anytime as mentioned before)

So now let's take a look at SDNY

SDNY = Currently 3 vacant seats for District Judges.

3 Trump appointed Judges so after filling 3 vacant seats there will be in total of 6 Trump appointed Judges. Here comes the funny part: SDNY currently has 17 active Senior Judges, 9 appointed by Clinton, 4 appointed by G.W. Bush, 3 by Reagan and 1 by Ford.

President Trump can potentially replace them all at any point he wants so instead of 3 vacant seats, there are actually 20 up for grabs in SDNY. That would mean Trump appointed District Judges would increase up to 23 in SDNY, the highly important District for investigations on Weiner evidence collection, Clinton Foundation , Epstein evidence collection and Ukraine. There are currently 4 Clinton appointed District Judges(including Chief Judge) 3 by G.W. Bush and a whopping of 15 by Obama(woah, it almost seems like he wanted to make sure he has full control of this important District)

So let's do the math here. When it comes to active District Judges, the DS have in total of 22 seats. Trump currently has 3 District Judges and 3 vacant seats to fill so he will soon have in total 6 District Judges. So let's say President Trump decides to replace all 17 Senior Judges how many Judges does he have then? 23. Oh wait, how many did the DS have? That's right, only 22 so President Trump outnumbers them by 1 and is in full control of this crucial court.
