OF ALL THE GUESTS AND ALL THE TOPICS…. National Review‘s Jim Geraghty caught an interesting segment on MSNBC this morning.

Rudy Giuliani is on MSNBC’s Morning Joe, talking about the fate of South Carolina governor Mark Sanford. Giuliani mentions that a lot of it comes down to performance. One of the other guests mentioned that a CEO who behaved like Sanford did would be replaced by the company’s board quickly; Giuliani said he wasn’t so sure; he said a lot had to do with performance, and he could think of at least three executives who were in a similar spot to Sanford. (He didn’t elaborate; did he mean adultery, or suddenly disappearing for a few days?) […]

Asked whether the forgiveness-depends-on-performance mentality was right, Giuliani said, “it’s just reality.”

I didn’t watch the segment, so I can’t speak to what viewers were told by way of disclosure, but inviting Rudy Giuliani onto national television to discuss consequences for a politician caught in an adultery scandal is hilarious, even by the standards of “Morning Joe.”

For those who’ve forgotten, Giuliani has been married three times. The first was to his cousin. He left his second wife, Donna Hanover, during his mayoral tenure by announcing it in a press release — before telling his spouse. After Hanover kicked him out their home for alleged serial adultery, Giuliani marched in a St. Patrick’s Day parade with his mistress. (In the divorce proceedings, Hanover accused Giuliani of serial adultery, alleging that Judith Nathan was just the latest in a string of mistresses, following an affair the mayor had had with his former communications director.)

Atrios tweeted this morning, “of course the cable news day began with rudy giuliani discussing the sanford affair on morning joe. any self awareness journos?”

Apparently not. Inviting Giuliani onto national television to discuss Sanford’s sex scandal is like inviting Barry Bonds on to discuss what should happen to a baseball player accused of steroid abuse. Sure, there’s some familiarity with the subject matter, but it’s not like there’s any degree of credibility.

Update: More on this from Jamison Foser, who noted that the segment included discussion of Bill Clinton, but not Giuliani himself.
