First of all: Pray.
1 Timothy 2:1-2 instructs us:
First of all, then, I urge that entreaties and prayers, petitions and thanksgivings, be made on behalf of all men, for kings and all who are in authority, so that we may lead a tranquil and quiet life in all godliness and dignity. 1 Timothy 2:1-2
"Whether or not your favorite candidate won, God maintains sovereign control and calls his people to complete dependence upon Him."
