For the price of the Iraq War, we could've funded Barack Obama presidential campaigns for the next 10,000 years. 
Barack Obama just raised a record-setting $150 million in September, pushing his total fundraising to $605 million.  If he raises the same amount in October he will have raised a total of $755 million for his presidential campaign.  The next 10,000 years will include 2500 presidential elections.  Similarly funding presidential campaigns for the next 10,000 years would cost $1.89 trillion, $1,110 billion less than Joseph Stiglitz and Linda Bilmes' estimate of $3 trillion for the total cost of the Iraq War.
