They quickly put that up there after Faux News declared the Pope was dead a day early. But on the primetime coverage last Saturday (4-2-05), when Mr. Olbermann was doing an excellent job (even Mediabistro's right-slanted TvNewser blog was quoting Mr. Olbermann), they paired him with Tweety.
Well, when Tweety was interviewing former Vatican ambassador Raymond Flynn, Tweety played politics and pulled out the discredited bullshit that former Pennsylvania governor Bob Casey was forbidden to speak at the 1992 Democratic National Convention because he opposed abortion rights. According to Paul Begala, who was a whole lot more involved with that convention than Tweety, Casey was passed on because he didn't endorse the ticket.
