The stimulus package Obama signed in February includes about $499 billion in new spending, and to date, the Obama administration has allocated about $158 billion to specific projects and programs. Most of that money has gone directly to state governments, which then disperse the money to prevent school layoffs, repair roads and fund social services. That contrasts with the $17 billion that Washington distributes directly to local communities.

Including the larger chunk of money given to state governments, the aid favors states that voted for Obama, which have received about 20% more per person,

The imbalance didn't start with the stimulus. From 2005 through 2007, the counties that later voted for Obama collected about 50% more government aid than those that supported McCain, according to spending reports from the U.S. Census Bureau. USA TODAY's review did not include Alaska, which does not report its election results by county.
