Are the Republicans actually dusting off the same old failed McCain campaign tactics? 
Whatever. It was stupid for him to say and his "energy policy" hasn't made it past that stage and onto anything of substance.
The McCain camp was right to drill him on that. $4.00 gas, $146 p/barrel oil and he shrugs off exploiting our own resources and instead of anything substantive he fires back with "inflate your tires", which was proven to not do jack shit let alone replace production from new oil wells.
I didn't buy completely in to the lamely named "Drill Drill Drill" as it was short sighted as well, but you have to do better than "inflate your tires", CAFE and windmills.
