"When George W. Bush became president in 2001, his main goals included restoring 'honor and dignity to the White House' after the Monica Lewinsky scandal, raising school-test scores and figuring out how to spend a record budget surplus. The next White House occupant will inherit the deepest housing recession in a generation, growing fears of bank failures, a sinking dollar, $4 gasoline and an economy bleeding jobs. He'll confront wars in Iraq and Afghanistan, mounting tensions with Iran and the U.S.'s flagging international reputation. Historians say the economic and foreign policy crises in Bush's wake will present either Democrat Barack Obama or Republican John McCain with the biggest challenges to a new president since Herbert Hoover left office during the Great Depression."
