Remember, the crowd telling the pollsters they were Evangelicals who voted for Obama were likely to be Democrats and they lie. Always assume Democrats always lie when it comes to politics.
You are making yourself excited about something that simply cannot be known from the data ~ even Rev. Wright's church is part of the Church of Christ (puritan) crowd ~ an ancient Protestant movement, yet he teaches BLT. We know it's BLT because we've heard his tapes and we know where those concepts come from. They didn't change their church name though.
Goodnight, Gracie!
