Rush Limbaugh, who has already said that Barack Obama looked like Osama bin Laden in a picture in which the Democratic presidential candidate was wearing Somali clothing, added on “The O’Reilly Factor” this week that Obama was “looking like [Osama bin Laden’s chief collaborator] Ayman [al-]Zawahiri.”

On a related note, I heard Limbaugh ranting today about how Obama is worse than Bill Clinton based on the overblown dispute over what an adviser allegedly told a Canadian diplomat:

[D]o you think Obama’s faithful give a rat’s rear end about the Tony Rezko deal and how Obama bought his house? You know, it strikes me… This is the kind of thing that we tried with the Clintons back in 1992, all of the character defects, the lying. It didn’t matter. It really didn’t matter. People were just so (sigh). People didn’t care about it. When we tried pointing out the character flaws of Clinton, it just didn’t matter. Now, this stuff with Obama is far more serious, and I’m not minimizing how bad the Clinton stuff was, but this is worse. This guy is actually incompetent. He is clueless. He has a Clinton problem in that he will just change a story on a dime, and make it sound like everybody else heard him wrong the first time.

It’ll take better material than that for Rush to turn Obama into Michael Dukakis.
