I've been a Christian for 20 years myself, and there is nothing more anathema to me these days than a politician who tries to use Christianity as a platform to grab political power. IT ALWAYS RUINS THE CHURCH!!!
If we all didn't learn from the negative results of Constantine's politicization of the church nearly 1,700 years ago, we may never learn. We got nearly 1,000 years of religious oppression, spiritual and doctrinal error (as the desire for money and power do corrupt even religious leaders) and a long, long road that we're still having to climb to get back up out of the abyss of scriptural and spiritual ignorance that the lust for power among those so-called Christian leaders foisted on us.
I will NOT vote for the corruption of Christianity into a political tool no matter what the good intentions may be of those who are candidates in that cause.
