Well?
A good politician is usually a greedy, corrupt, backstabbing liar who, nevertheless, is relatively adept at persuading people to peaceably work out their differences through bribery and compromise. A bad politician is usually a greedy, corrupt, backstabbing liar who lacks either the will or the competence to persuade people to peaceably work out their differences through bribery and compromise. In other words, the alternative to civil politics is civil war. Today, we have far more bad politicians in high office than good ones. At the head of the whole rotten pack is an authoritarian narcissist who has very little political experience and has never shown much competence in uniting people. What could possibly go wrong?
