Offshore Drilling! Yes or No?
Bush and McCain have reversed their position on off shore drilling and are now calling for Congress to lift the ban, claiming it will ease dependence on foriegn oil and reduce prices at the pump.
"Senator McCain, the Republicans' presumptive presidential candidate, is opposed to opening up Alaska and had previously backed the moratorium on drilling in coastal waters.
But speaking in Houston on Tuesday, Mr McCain called for the ban to be lifted to help counter US dependence on foreign oil.
"We must take control over our own energy future and become once again the master of our fate," he said.
Mr McCain said the US had enormous energy reserves and was acquiring methods of using them in clean and responsible ways.
Senator Obama dismissed Mr McCain's call as "political posturing".
"His decision to completely change his position and tell a group of Houston oil executives exactly what they wanted to hear today was the same Washington politics that has prevented us from achieving energy independence for decades,"
Mr Obama said.
He called for conservation and the search for alternative green energy supplies.
Analysts say drilling for offshore oil and developing alternatives will both prove slow to reduce US dependence on imported oil."
