We are to "render to Caesar the things that are Caesar's." We will have to give an account of ourselves as to what we did with evil and not voting is trying to be neutral and there is no neutral as far as God is concerned. Are we part of the problem or part of the solution?
As long as we are in an imperfect world before the Millennial Kingdom of Christ we will always be choosing between the lesser of two evils; no one is perfect! It is just as wrong to exalt someone as a hero and "savior" than it is to demonize. God is a jealous God and doesn't appreciate us thinking someone is the panacea for our societies woes. The choice will always be between the lesser of two evils until Christ comes--so don't be disillusioned or disenchanted! I want as little evil as possible, don't you? Soli Deo Gloria!
