Bush: 'I take responsibility'

George W. Bush took responsibility on Tuesday for failures in the federal government's response to Hurricane Katrina.

"Katrina exposed serious problems in our response capability at all levels of government, and to the extent that the federal government didn't fully do it's job right, I take responsibility," Bush said. "I want to know what went right and what went wrong."

Just what does taking repsonsbility mean to an administration that so highly prized 'accountability' during it's campaigns for office? How will this affect the constant reference to the 'blame game' by members of the administration?
