Midwestern levees are bursting. Polar bears are adrift. Gas prices are skyrocketing. Home values are abysmal. Air fares, college tuition and health care border on unaffordable. Wars without end rage in Iraq, Afghanistan and against terrorism.
The Mayans were also wiped out by disease, weren't they? Clearly they know everything.
Edit: Although peculiarly enough, some others say the world will end to a Muslim leader that is a great orator. If Obama is elected, his term would end in 2012, which would tie in with the Mayans prediction about the world ending in 2012. (I'm not saying he's Muslim, although his name is a "Muslim" name)
