Make Him Bush's Moral Issue
The public is largely out-of-the-loop on the Republican dirty tricksters. They don't grasp that they are being hoodwinked time again by the same tactics and guerilla politics. I say take it away from Bush. Name Rove in speeches and in the next debate, and make it a moral question that the president would have someone of such questionable character as his chief advisor. Go down the litany of tricks that he has pulled in the past. Bugging his own campaign office and blaming it on the opposition... The fake pollsters asking about McCain's mixed-race child... The fliers left on cars in church parking lots lying about Ann Richards' sexuality... And then ask if someone who proports to be of such moral character would keep this kind of person as his chief advisor. Make Bush answer for it. Even raising the issue would place the debate in the press who would then have to report on Rove's past and his intimate link to Bush. Facing it directly, not just protesting the lies and tricks after the fact, but making the trickster the issue denies them much of their covert ability to use sneak attacks in the last stages of the campaign (and they will). If it is loudly put into the public's mind, it will suppress much of their ability to fool the public. The public will say, "Ah, this is just what Kerry was talking about." It will also reflect deeply on Bush's moral character because their tactics run counter to Christian ethics. Use their past against them by making it an issue of morality.
