Does the whole issue of Barack Obama being a member of Jeremiah Wright's church affect your vote?

Until today I was a staunch Obama supporter. Then I was again reminded of his ties to Jeremiah Wright. For those of you who don't know who he is, search for him on youtube, he is a racist bigot who says "God damn America" in a church and calls the country U.S. of KKKA! I'm having a difficult time coming to terms with this. Will this affect your vote? Why or why not?
