This AP story points out Obama's hypocrisy on the energy issue:

"In stumping Tuesday in this key battleground state, Obama sought to link the troubled economy with Republican policies and offer his own energy plan in contrast. He has tried to cast McCain as more concerned about oil company profits and drilling than an overall energy strategy.

However, Obama himself voted for a 2005 energy bill backed by Bush that included billions in subsidies for oil and natural gas production, a measure Cheney played a major role in developing. McCain opposed the bill on grounds it included billions in unnecessary tax breaks for the oil industry."
