"Accepting this different road to 270 electoral votes will be difficult for many in the Democratic Party who have spent decades searching for the silver bullet that would bring white blue collar workers home to the Democrats. Unwillingness to accept this was at the heart of Hillary Clinton's electability narrative. Her narrative, that she was uniquely positioned to bring Reagan Democrats back home in November was prima facie absurd, but got an enormous amount of traction and was largely unchallenged in the media or, frankly, by the Obama campaign. The reality was that Clinton remained unpopular with this group, with 55% of white voters who had not completed college viewing her unfavorably in an April, 2008 AP poll.
The broader notion, however, that the only way for the Democrats to win was by sweeping the rust belt, is so widely accepted that Clinton's argument went unquestioned. The question that should be asked is that given that in each of the last two presidential elections the Democrats tried this strategy and failed, why would Clinton's chances in 2008 be any different. In 2004 the Democrats ran a war hero, albeit a liberal and extremely wealthy one from the Northeast, against an unpopular president who was viewed as mishandling an unpopular war, and still managed to lose Ohio, and, of course, the election. Betting the farm on the notion that in 2008 the Democrats can carry Ohio and win the election by running very liberal and very wealthy senator from the Northeast with no war record against a Republican who is a war hero and who has been critical of the mismanagement of an unpopular war, seems to fit at least one definition of insanity-doing the same thing over and over and expecting different results."
