A question regarding Rev. Wright's ranting

Was Reverend Wright working for the Clintons, in order to hurt Senator Obama's chances of winning?

After all, exit polls in Indiana showed that many of the people who voted against Senator Obama used Rev.Wright's grandstanding as an excuse for voting for Hillary Clinton. Moreover, neither Wright nor either of the Clintons have raised the fact that he was, personally, invited by them to the White House, for counseling, when Bill Clinton was going through the Monica Lewinsky problem. Therefore, what was different about Wright then that made Hillary Clinton lambast him and his beliefs, during the nationalized television debate in April? And why did Senator Obama not mention that? He surely knew.

In fact, we also know that, just a few days prior to the debate mentioned above, the Clintons' former pastor was convicted for sexually molesting a seven years-old girl, and sentenced to three years in prison. Why was that not brought up by either candidate or the government- and corporate-controlled media?
