I don’t think it’s bad NOT to use Rev. Wright. With the short-term memory of most of the electorate, they’ll first ask “Who?”, then when they hear it was something from four years ago, they’ll dismiss it as ‘ancient news’. It might excite some conservatives, but most folks will just ignore it. I think it will be more important to concentrate on the economy, and the idea of religious liberty.
It’s ok to go negative, but not before making sure people know what you are “For”......don’t put the horse before the cart.
