Leaders that do not honor God in everything they do will seldom end well. They may rule for a very long time (in human terms) but their rule will never be blessed. Any person placed in authority, elected or appointed need to be aware that all positions are granted by God.
There is no position other than that granted by God for His purpose and His plans. While it may be hard to see and or understand His purposes and plans, nothing ever happens by accident.
Many leaders fail to realize the simple truth. All position is at God's will. So many still fail to know that to go against God's word is foolish. The really crazy thing is, these leaders will say they are God fearing, support policies that are totally against God's word, and then end with a God Bless You.
How weird is that? Asking for a Blessing from the very God they choose to deny?
