I think energy independence functions as a nice umbrella concept that takes in Kerry's strong points - the environment and foreign policy - and puts them into a central vision for America's future.
I think Kerry's plan for universal health care was absolutely brilliant (although the campaign never did a great job of putting it out succintly). But the issue just didn't seem to fit his public persona.
Peggy Noonan was right (in a way). Character matters. Now we all know that Reagan's character was less than noble, as several of Kerry's investigations pointed out, but you cannot underestimate a well-crafted public "character."
Despite being a life-long hunter, Kerry seemed out of character with a shotgun in his hand.
Kerry's character is being a foreign policy wonk and something of a brainiac. It is ridiculous for him to suggest that he is a "regular guy." In fact, he doesn't even seem much like any Vietnam vet that people have come to expect. If I can be brutally honest, I don't think he did a proper job of connecting his war life on the river with his policy wonk persona (i.e. why it mattered, beyond resume fodder).
Personally, I think that's where blm was dead on. Her diehard refusal to join the sprint away from Kerry's investigative experiences helped to illuminate the perfect bridge for a warrior returning to America in the face of Nixon's failed war and the utter destruction of the public's trust in government institutions. God bless her for it. I hope somebody finally listens to her wisdom.
Kerry should play to his character, because doing otherwise makes him look disingenuous.
His record on the environment and the depth of his foreign policy experience are widely known. Staking his claim to history as "The Energy Independence President" plays not only to his actual strengths as a person, but also plays to his history and the media/public's perception of his character.
As for Iraq, Kerry should push hard - hard - for withdrawal. But I don't think the GOP will allow Iraq to remain a dominant issue on the table. They will pressure Bush to use the surge as political cover and, for all intents and purposes, skidaddle.
Therefore, Kerry needs to - as he put it in 2003 - "play to where the puck is going to be, not where it is now" (I'm paraphrasing).
He needs to set out a broader fight on terrorism that aims to effectively end Middle East hostility to the U.S. in 20-25 years by becoming independent of oppressive regimes like the House of Saud through renewable domestic energy and by becoming a central force in improving the quality of life for everyday Arabs (and Persians).
Oh, and also promising to "blow the terrorist S.O.B.s straight to their preferred oblivion" by taking them head on, not pussyfooting around like the Tora Bora debacle.
