I choose a church based on the church and my particular denomination. Pastors come and go within a given church. And yes, I do go to a church where I don't agree with many of my pastor's political views. I am pro-choice and I am certain my pastor is anti-abortion. Should I leave the church???? Of course not.
Obama chose a church that was presided over for 20 years by a racist. Think that says anything about the church? About Obama? If not, then you are just completely unopen to reason in regards to judging the man. He is your candidate and nothing he says or does is going to turn you away from him.
