"When the righteous increase, the people rejoice, But when a wicked man rules, people groan." (Proverbs 29:2)
At this link in Live it! an article on "How Will You Vote" by Kay Arthur is well written. I highly suggest reading it. It explains the verse above along with:
Proverbs 28:2 "By the transgression of a land many are its princes, but by a man of understanding and knowledge, so it endures."
There are other verses as well. These two set the stage for the article. Kay Arthur is a wise Pastor of Precept Ministries. She has done plenty of travels and research.
