After two years of campaigning and a night of celebration, the Obama-Biden administration "will inherit problems of historic proportions" not seen since FDR began his term during the Great Depression, Dan Balz writes in the Washington Post. Top on the agenda: a sinking economy and a war on two fronts. Aiding Obama's task? His diverse "new coalition" of voters that led him to the Oval Office provided a "personal mandate" for action. Advisors caution they learned from 2006 not to aim for an "unabashed liberal government" and that Obama will "govern inclusively" and will face budgetary hurdles.
