Do you remember Michael Dukakis? Watch this ad and tell me if it sounds like things we're hearing now.
And for a special bonus -- check out the sources listed on the second link, then tell me when left-wing columnists like Joe Klein and E. J. Dionne's views became dispositive on an issue. Do you suppose that if McCain ran an ad citing Sean Hannity's views as evidence for an assertion that most people would accept it?
