I don’t know where you get this idea but the president does not have the authority to issue mandates that dissolve the government. The president cannot act free from constitutional law. He cannot stack federal government with politicians who are loyal only to him. That’s why we have elections, and no, he cannot ban elections.
That's all very nice and true
in theory, but this is reality we live in. Are you aware that we don't
have to follow the rules? No, it's true! You can break rules and laws! What happens if you do? You get investigated, arrested, charged, tried, convicted and sentenced, all of which Trump's lawyers are arguing RIGHT NOT do not apply to him. His lawyer just argued in court, literally, that if he were to shoot someone the police could not only not arrest or investigate him, they couldn't even legally
stop him from shooting the next person. If that argument holds then you've just taken the entire justice system, right down to the lowly beat cop, out of the picture. That includes the courts, 1 of the 3 branches of government.
They are also arguing in court that Congress, who has a Constitutional mandate to check the president’s power, cannot investigate him. They are refusing legal subpoenas and simply claiming the law doesn’t apply to Trump because it is the investigation that’s illegal, not the crimes the president committed. If that holds then you’ve just take Congress out of the picture, the 2nd of 3 branches of government, leaving only the executive branch, which the president has total control over.
And the story broke yesterday that the DOJ has started a criminal investigation into some of Trump’s political enemies. Anyone involved in the Mueller investigation is currently at risk of being criminally charged for imaginary “crimes” involved in investigating the president. They have already fired and smeared ALL of the major characters in the FBI and CIA for doing nothing but their jobs. Now you actually have the top levels of the criminal justice system, courts aside, actively working for Trump and, in fact, the very criminal justice system that is supposed to investigate wrongdoing is actually actively working to cover up wrongdoing. Barr refused to investigate the whistleblower complaint. He didn’t even look into potential criminal activity. But hey, he’s looking into Obama as we speak!
Currently the ONLY thing that could be done to remove him from office is for Congress to vote to do so. Voting against Trump is politically poison for Republicans. If they remove him they, themselves, will be removed in the next elections. And all of the Republicans who had half a ball have already resigned or decided not to run again. So the chances of him being removed from office by Congress are slim.
So what if Congress won’t do that? What if they do and he refuses to leave? Who’s going to make him? Who’s going to stop Bar from removing Schiff from office by having him arrested for his “illegal” impeachment proceedings? Granted this is an unlikely scenario, but it is scary and, the way things are going right now, actually remotely possible.
