That is utterly ridiculous! Based on what facts do you utter that hyperbole?!
You have a far right Christian conservative currently in the White House. I would say the GOP image as a fiscal spendthrift party has solidifed. The 'scratch my back for donations' image has not only been magnified, it's thriving. As far as I can see, having a President on the right has not not helped prevent the creation of the same image you are concerned that Giuliani would propagate.
We see it already in the hyperbole surrounding the Duke Cunningham scandals re the GOP. Corruption charges stick to the GOP, the Dems wiggle out because the MSM gives them a huge pass.
Why would Guiliani have the same issues but have them even more closely connected to the Presidency ? Just look at his associates - try Kerik as an example - and the projects undertaken by Guiliani’s firm. If you don’t think a negative image of Haliburton was hung around Cheney’s neck over and over to taint his reputation, just wait til the MSM start talking about all this 24/7.
