In a Democracy, laws are established or repealed by the majority. The rule of law's protection of minorities from the whim of the majority in a democracy is no protection at all.
It has been well said that a democracy is two wolves and one sheep voting on what to have for dinner.
But in a Republic, a written Constitution safeguards the rights of the individual and the minority, despite the whim or panic of the majority.
Thus, in the American Republic, all citizens are in theory protected by law, in spite of the election of a lunatic. But the law must be enforced against a lawless president, and it is done by way of the remaining two branches of our government (Congress and our courts).
