You have a great point on leadership, abowles. One of my recurring themes is things happen, esp in a democracy because the general public allows it.
Look at some of our leaders. FDR had a mandate to legislate the New Deal, LBJ Civil Rights legislation in the wake (pardon the pun) of JFK, Reagan had support of limited government in the 1980's.
Now look at our energy policy. Gerald Ford got CAFE standard in 1975 - gutsy for a Michigan Republican, but it was when the 1973 Oil Embargo was still fresh on the nation's mind. Only three years later, Jimmy Carter's "Moral Equivalent of War" energy speech was a non-starter - the public just was not interested.

I usually disagreed with Jimmy Carter, but he was right-on in this case.
My gut feelings is there are plenty of Republicans that could have been in the White House now that would have had a more serious energy policy than this one. Again, I would not isolate the blame game on the Bush administration and the oil companies. Be sure to include a sizable amount of the driving public that insist on driving sub-20mpg vehicles that far exceeds their needs.
