WASHINGTON — President Barack Obama's fiscal 2010 budget request is only the latest in a series of recent massive federal spending programs that have arrived so fast and furiously that many Americans might have trouble keeping track of them all. Here are the main ones:

• The emergency stimulus package, enacted two weeks ago: $787 billion over two years.
• The bank bailout package, enacted in October: $700 billion.
• The federal loans to GM and Chrysler: $17.4 billion so far; $21.6 billion more requested.
• Obama's request last week for a new mortgage-foreclosure relief program: $275 billion.
• Treasury provided $200 billion in September to shore up Fannie Mae and Freddie Mac as it placed the mortgage-finance giants in federal "conservatorship" indefinitely.
• Federal Reserve's two-year, $85 billion loan to American International Group in September, in exchange for a roughly 80 percent stake in the global insurer.
• Funds for the rest of fiscal 2009, through Sept. 30: $410 billion.
• Total fiscal 2009 budget: $3.94 trillion.
• Total Obama budget request for fiscal 2010: $3.55 trillion.
