WASHINGTON—Following a strong performance by the Democratic nominee in Tuesday's presidential debate, political analysts overwhelmingly agree that Sen. Barack Obama has all but clinched the much-sought-after "Joe Cabernet Sauvignon" voting bloc. "Once again, Obama has proved his ability to speak directly to all the regular truffle-oil-guzzlin', Nabokov-readin', opera-attendin' folks who play such an important part in deciding this election," MSNBC commentator Chris Matthews said of the Illinois senator's strong connection with the nation's hardworking gallery owners, literary critics, and gourmet-cheese purveyors. "His strong rapport with the average haut monde Joseph could tip the scales Nov. 4." Sen. John McCain's recent attempts to reach out to this constituency by wearing an elegant silk ascot were not well received, having been described in most quarters as "pandering of the most contemptuous variety."
