It is clear that you know which most meets your beliefs, and that based on years of experience discussing hundreds of issues with you.
Please consider, though: Since the Apostle Paul is on record saying that we shouldn't do evil so that good will result, then I think it is not at all a given that God wants you to vote for Romney.
After I typed "Rather, which of those candidates does God want me to vote for?" it occurs to me that I am making the same mistake the Apostles did when they cast lots to replace Judas:
They would never have considered Saul (Paul) who was persecuting the Christians. And yet subsequently God chose him, personally, emphatically and in power.
For ye have heard of my conversation in time past in the Jews' religion, how that beyond measure I persecuted the church of God, and wasted it: And profited in the Jews' religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers. But when it pleased God, who separated me from my mother's womb, and called [me] by his grace, To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood: Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.
Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days. But other of the apostles saw I none, save James the Lord's brother. Galatians 1:11-19
