Rudy Giuliani and George W. Bush have more in common than just mendacious, authoritarian streaks; they also employ the same strategy when facing a scandal: ignore it and hope it goes away.

Yesterday, for example, we learned about the latest in a series of lies regarding the Shag Fund controversy. In response to the revelations, the former mayor has decided he doesn't want to talk about it.

Rudy Giuliani tried to ride out new questions Friday over taxpayer-funded chauffeur services that witnesses and sources said were provided to Judith Nathan before her affair to the former mayor was revealed in 2000.

The Republican presidential candidate, asked by a Daily News reporter after a campaign event in Chicago about Nathan's city-funded wheels, nonanswered "Thank you," and later "Have a good night."

Moreover, the Daily News also emphasized today that when it came to providing a taxpayer-financed security detail to Giuliani's then-mistress, the timeline doesn't ad up. Giuliani and Bernie Kerik said Judith Nathan needed NYPD protection starting in early 2000, because of unspecified "threats," which may or may not have actually happened. As the article points out, "How Nathan could have become the target of a threat before she became a public figure has not been explained."

The Daily News added a provocative quote from Dick Dadey of Citizens Union, an NYC public-interest watchdog group: "If Nathan was provided police protection prior to their being a security-threat assessment, it probably was an illegal use of city resources." (emphasis added)

To be sure, if Giuliani did break the law here, the statute of limitations has probably run out. In the context of a presidential campaign, though, it's probably not an effective pitch: "Vote Giuliani: Because He Can No Longer Be Prosecuted."
