I have a request for everyone voting: Hold your candidates accountable for their actions. When Bush and Obama misused executive privilege, many of their supporters were silent. Please don't be silent. Hold our politicians to a higher standard, pray for them to make wise decisions, and follow JFK's advice to "ask not what your country can do for you, ask what you can do for your country." We need to give more than we take.
Wikipedia reports that British politician John Hobhouse originated the phrase "His Majesty's Loyal Opposition." Sometimes Christians must serve as the "loyal opposition" by opposing immoral legislation and destructive government policies.
Although Jesus was not a politician while he lived on earth, He requires us to be subject to the government. Romans 13:1-4 teaches us:
"Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God. Therefore whoever resists the authorities resists what God has appointed, and those who resist will incur judgment. For rulers are not a terror to good conduct, but to bad. Would you have no fear of the one who is in authority? Then do what is good, and you will receive his approval, for he is God’s servant for your good. But if you do wrong, be afraid, for he does not bear the sword in vain. For he is the servant of God, an avenger who carries out God’s wrath on the wrongdoer." (English Standard Version)
I believe one of the reasons Jesus wasn't a politician was because He wanted us to know that his kingdom is not of this world. Also, Jesus challenged conventional thinking by teaching, "The greatest among you shall be your servant." - Matthew 23:11 Also Jesus may have avoided politics to set an example for us so that we wouldn't turn politics into an idol. God should come first always.
