I guess Barack Obama also crucified Jesus and kidnapped the Lindbergh baby too

Yup, the economic free-fall we're in is all about Barack Obama. The colossal mismanagement of the nation's financial behemoths had nothing to do with it:

America's five largest banks, which already have received $145 billion in taxpayer bailout dollars, still face potentially catastrophic losses from exotic investments if economic conditions substantially worsen, their latest financial reports show.

Citibank, Bank of America, HSBC Bank USA, Wells Fargo Bank and J.P. Morgan Chase reported that their "current" net loss risks from derivatives — insurance-like bets tied to a loan or other underlying asset — surged to $587 billion as of Dec. 31. Buried in end-of-the-year regulatory reports that McClatchy has reviewed, the figures reflect a jump of 49 percent in just 90 days.

The disclosures underscore the challenges that the banks face as they struggle to navigate through a deepening recession in which all types of loan defaults are soaring.

The banks' potentially huge losses, which could be contained if the economy quickly recovers, also shed new light on the hurdles that President Barack Obama's economic team must overcome to save institutions it deems too big to fail.

While the potential loss totals include risks reported by Wachovia Bank, which Wells Fargo agreed to acquire in October, they don't reflect another Pandora's Box: the impact of Bank of America's Jan. 1 acquisition of tottering investment bank Merrill Lynch, a major derivatives dealer.

Federal regulators portray the potential loss figures as worst-case. However, the risks of these off-balance sheet investments, once thought minimal, have risen sharply as the U.S. has fallen into the steepest economic downturn since World War II, and the big banks' share prices have plummeted to unimaginable lows.

With 12.5 million Americans unemployed and consumer spending in a freefall, fears are rising that a spate of corporate bankruptcies could deliver a new, crippling blow to major banks. Because of the trading in derivatives, corporate bankruptcies could cause a chain reaction that deprives the banks of hundreds of billions of dollars in insurance they bought on risky debt or forces them to shell out huge sums to cover debt they guaranteed.

Now someone tell me how this is Barack Obana's fault. I'm not kidding. Tell me. But don't go posting recycled talking points from Rush Limbaugh and Fox News in the comments. It's a waste of time and it ought to be embarrassing to anyone who does it. I want someone to tell me how Barack Obama made all these bank executives and board get embroiled in this stuff.

You can't do it. Not and sound like you're sane.
