"The Obama campaign was hoping to reintroduce Mr. Biden this week as running mate attack dog. But his penchant for verbal rambling ensured that much of the attention he drew was unwanted: he said wealthy Americans had a 'patriotic' duty to pay more taxes, a remark the McCain campaign mocked relentlessly.
Yet Joltin’ Joe has also become a fascinating Off Broadway spectacle in his own right. He is a distinctive blend of pit bull and odd duck whose weak filters make him capable of blurting out pretty much anything — 'gaffes,' out-of-nowhere comments (pivoting midspeech to say 'Excuse my back!' to people seated behind him), goofy asides (tapping a reporter’s chest and telling him, 'You need to work on your pecs.')"
