Wall-to-wall cable convention coverage. It can make even Chuck Todd (MSNBC’s “goateed guru”) look less-than-sharp.

During a David Shuster report on Michelle Obama getting her bearings at the convention podium (or, “Michelle Obama Walks Through Pepsi Center Just Hours Before Speech”), Todd asked:

David…you can usually tell when people do these walk-throughs, they’ll go back to something a second time because something bothers them about something. See anything like that?

For the record: no, Shuster did not “see anything like that.”
