I hope you aren't under the impression that that particular scenario would bother the Bush Haters on this forum.
You're right. It's not about 'sending the President a message'. It's about trying to destroy the man or at least get attention from the liberals so they can use it to create the perception that 'some in the GOP are not happy'. These malcontents are no different than Arianna Huffington or the 'republicans for choice' that pop up every election.
