(Proverbs 29:8 KJV) Scornful men bring a city into a snare: but wise men turn away wrath.
It makes a difference the type of leaders a “city” (7151) picks. Keep in mind that democracy as we know it was isolated to a few locations if it existed at all. Power came from the top. Governors of provinces were appointed by the king. For the most part cities were also under his control. In spite of that autocratic understanding of government the leaders would often have councils of civic leaders. This got more common as you moved toward the grass roots. Those leaders would have some input into some of the choices for civic leadership. However they are appointed, it makes a difference.
If you need an example, look at what is going on in San Francisco. There are constant jokes going on about how drug needles are handed out by the city leaders but you can go to jail for giving someone a plastic straw. People defecate on the streets with nothing done about it. It was also one of the early centers of homosexual political power. Could there be cause and effect here? Solomon seems to think so.
So? Christians with morals may not be able to elect godly leaders but we can still make our voice heard. If no one listens then look for a chance to vote with your feet. I will admit that is totally personal opinion.
