No, Bush is.
Now that we're over that simple fact let's talk about Jimmy.
His biggest fault was his including his brother Billy in important matters. Boy, was this wrong.
However, his non-Rambo approach to the Iran Hostage Crises after one failed attempt, which was not his fault, was probably the best way to not have anyone killed. Too many Americans watch too many exaggerated movies about gutsy, gun blazing rescues. These, people, for the most part, are fantasies. Please try to drag your brains away from Hollywood entertainment for a bit and try to comprehend reality. This is something Bush can't do and that is why we are at war (however undeclared) on Iraq and creating more and more hatred of the US.
The US dependency on oil is part of an overall plan to use the rest of the world's resources before using ours. Even if we drilled and refined more oil ourselves the market would still result in high oil prices as the market and oil companies determine. Do you wish to keep a free market environment in the world or do you want to dictate oil prices through government?
In Jimmy Carter's presidency the fact of high inflation was a world wide issue.
Inflation world wide caused high unemployment every where.
The oil crises was everywhere also having been manufactured by Big Oil.
Bush, on the other hand, began office with a good economy and an economic surplus and continued on to leave the government on the verge of having no money at all five times. He's had to beg before Congress five times to raise his borrowing limit. How are you Bushies going to pay off this dept with a failing economy? At a time when the world economy is still relatively strong though feeling the crunch of the costs of oil too.
