Biden's performance was beyond bizarre -- it was unworldly. I'm not a druggie but I don't think a bad trip on acid could have been more unsettling. The moderator, Martha Raddatz, was equally as dreadful. I had to keep rechecking the scorecard to remind myself who it was that had actually signed up to debate Ryan. 

Sure, Ryan could have interrupted Biden's insane ravings with the truth -- but then why bother? When your opponent is energetically making a complete a** of himself then by all means step aside and let him optimize the moment. If I was Ryan I would have thrown in a "preach on, brother!" or two in encouragement to Biden.
This election is all over, as I have been predicting for months. I'm so certain of a Romney romp that I'm growing bored with it all.
