That is the question that this article asks. And what is the author's answer: vote Republican. This time that is exactly what the writer says: "If Christians cannot vote in good conscience for the Romney/Ryan ticket due to the Mormon connection, please consider stopping the modern King Herod by voting against President Obama. That would be the 'R' selection on the ballot."
As I have written before, Romney being a Mormon is the last thing I am concerned about. And as many times as I have said it, I will say it again: Voting for the lesser of two evils is still voting for evil. Now, I don't believe that Romney is the lesser of two evils. On some things he is and on other things he isn't. But even if he were clearly the lesser of two evils, voting for him would still be voting for evil. And Christians are told to "abstain from all appearance of evil" (1 Thessalonians 5:22). The writer of the article in question says that by not voting for Romney (whether by not voting or voting for a third party) you will be helping Obama to get reelected. But doing evil so that good may come is still doing evil (Romans 3:8). Christians should be doing what is good and not evil and leaving the consequences up to God.
