Stupid questions.
The Deep State has existed in some form as long as the country has existed, but it did not become more powerful than the government until 1913. It has become increasingly more powerful as time has gone by.
Banking, Wall St., & Industrial, monopolies, along with the Military Industrial Complex.
Trump ran against the swamp, which is another name for the deep state. He was well aware of the swamp; insider deals. Trump did not take donations from the swamp donor class, who was the ruling class. This defiance has made Trump an all out target. Once in office, Trump realized he underestimated the reach and lawlessness of the deep state. It was not a small group but was a large organization of party loyalists and appointees. Much of the deep state tactic is based on foot dragging, leaks, defiance and propaganda at all levels.
For example, CNN and other propaganda arms of the deep state, will not report the real news of how the Democrats broke laws, using government resources to spy on an opposition candidate. This is way worse that anything Nixon did, with Nixon previously used as the Democrat benchmark for executive corruption. Obama is the new benchmark. Nixon had a couple of amateurs break in into the DNC headquarters. The Modern Democrats under Obama used the FBI and Justice Departments to do this to the Republicans and Trump campaign at Trump Towers. The DNC took Nixon tactics to new heights. The swamp has to keep this evidence unconscious, by focusing on fake news and gossip.
Typically the deep state works behind the scenes, but this cycle is different, with the deep state pulling out all the stops, in a public way. The reason is the deep state did a miscalculation and did not expect Trump to win. This made it impossible for the deep state to clean up all the loose ends, that resulted from spying. Trump has also proven to more durable than anyone calculated, which has emboldened swamp opposition. Many Republicans have been working to gather loose end evidence.
The only thing that is preventing the defeat of the current deep state, is Jeff Sessions. Sessions appear to be foot dragging, in terms of addressing the Democrat party swamp corruption. My guess is Sessions is fully aware of the deep state Democrat corruption, but he is not yet convinced that Trump is here to stay in the long term. Sessions is procrastinating, less he acts too soon and he becomes the target of the deep state. Session may be calculating the possibility of a Democrat win in the midterms. This would initiate plan C, which is a push for Trump impeachment, by the Democrats and the deep state. If Trump loses Sessions does not wish to be on the side against the swamp. However, if Trump wins, then Session can cover this butt. Sessions may calculate that he needs to help Trump create justice, soon than later. There is still time before the summer campaign season. Trump's approval rating has gone up and Russian collusion is the least important issue to American voters.
Another problem for Sessions is the current deep state corruption, goes back to the Clintons and Obamas. This creates a problem, for a government elite purist, of having to drag the office of the president through the mud. This is something bigger that party squabbles. This is normal swept under the rug since nobody ever campaigns against the swamp. Sessions is in new territory, for himself. Sessions may also be more loyal, in spirit, to a fellow good ole boy insider, like Bill Clinton; two southerners, than to a loud mouth uncouth outsider yankee like Trump. Session is paralyzed with indecision.
Trump can't fire Sessions, since that means Rosenstein takes over. Rosenstein is part of the deep state corruption, since he was the one who wrote off on the fake Clinton paid for dossier, used by the FBI, to get a FISA warrant. Trump would need to fire Rosenstein and may be without an AG, since the deep state will use this as an opportunity to undermine nomination of any new AG who is willing to take on and harm the deep state. The Democrats will not go along with any nominee, that could potentially put half the DNC leadership in jail on corruption charges. Trump may have to apply pressure on Sessions to do the right thing and not the selfish thing.
I would like to see Trump fire Session and Rosenstein and nominate Chris Christie as the new AG. He is ready to a fight against the Democrat corruption machine since he has a chip on his shoulder for the actions against him. The deep state may find it in their best interests to approach Sessions and tel him to proceed, but at 50% enthusiasm, to buy the swamp some extra time.
