If you search your own Constitution or just do a simple search on the internet about this., for example "Is the US President the leader of the people or are it's citizens who are in charge" I think both you and many others would be shocked at what you will find. There are multiple Scriptures in our Bible that speak of the Judges,masters leaders ect. which do exactly apply to what your referring to but Romans 13 in specific verses 1 and 2 points out that they are ordained by God.
This being the case in Scripture it is extremely important understand that if for instance in the UK they do have kings and Queens and so speaking evil of him/her would be in direct violation of these Scriptures. In the United States of America on the other hand in our Deceleration of Independence and in the structure of our Constitution we the people have no king or Queen that retains power over us and we the people elect public officials to enforce our laws and decrees in our behalf. So if We The people are then the leaders of our nation it is then important to examine who exactly is speaking evil of who. In the many branches of our government the POTUS is head of the Executive branch and our government is structured this way to limit the power of any one branch over we the people.
In direct opposite of what seems to be thought two hundred and fifty years ago God the Almighty ORDAINED THE LEADERSHIP AND AUTHORITY TO WE THE PEOPLE NOT TO ANY KING OR QUEEN. And so also in direct opposite these public servants that we(we the people) elect surly better watch what they do and say against THEIR LEADERS WHO ARE ORDAINED BY GOD. You,me and every citizen of this nation were ordained by God as the leaders of this nation do not let any movement nor political party rise up and overthrow your freedom by insisting they are your ordained King or Queen and that we can no longer put them out of the public office we have put them in. https://www.biblegateway.com/passage/?search=Romans 13&version=KJV
