Obama is playing good cop to Bush's bad cop, letting EPA know that his administration will not deny facts but be guided by them.
Continuing efforts to overturn more of the last administration's policies, President Obama signed a presidential memoranda today requesting the EPA consider approving a waiver that will allow 14 states to set their own stricter automobile emissions and fuel efficiency standards.

Obama also signed a memorandum directing the Department of Transportation to expedite finalization of more fuel-efficient standards for the auto industry to cover 2011 model-year cars.

"California has shown bold and bipartisan leadership through its effort
to forge 21st-century standards and over a dozen states have followed
its lead. But instead of serving as a partner, Washington stood in
their way," Obama said.
"Rigid ideology has overruled sound science."
