A better analogy would be that you are dying of kidney failure. Your only choices are: (1) elect to go on dialysis (i.e. vote for the lesser of two evils) and do whatever you can to get a transplant (a better choice next election) before it kills you, (2) give up, do nothing and wait for death to claim you (don't vote), or (3) go ahead and shoot yourself (vote for the Democrat) so you can die quickly and get it over with.
Or, you could try simply doing the right thing and leaving the results to God.
It’s what our greatest President recommended.
“If, to please the people, we offer what we ourselves disprove, how can we afterwards defend our work? Let us raise a standard to which the wise and the honest can repair. The event is in the hand of God.”
- George Washington
