Trump never had free reign like the brutal dictators of the world do. He had to please everyone including his enemies, so of course he had to mix some lies with the truth to make the liberals happy.
Guess what? That's the difference between a dictatorship and a representative democracy: you have to make deals with those that disagree with you. That does not excuse lying.
I personally believe the president should have full power to run the country as he sees fit, without having to please his enemies all the time. It's like boxing with one hand tied behind your back so your damned either way.
Fortunately, those who wrote the Constitution disagreed with that viewpoint. They did not want an imperial presidency. Instead, they set up checks and balances: the power of the Presidency is restricted by Congress and the Courts. The Congress is restricted by the Courts and the veto. The Courts are restricted by the President choosing and the Congress approving.
So, yes, a President does have to deal with those who disagree with him/her *because that's how the system is designed*.
As an ultra conservative far right person, I believe it's the best form of government, because it acts in the best interest of the public at large. The public are generally dumb as sheep, they don't know what's good for them so they need someone to have complete power to do the job properly.
No, a dictatorship (which is what you describe) is NOT the best form of government. A *true* conservative would understand the checks and balances in the Constitution and uphold those as opposed to promoting one-party rule and rule of the President by fiat.
