Explained: Why McCain favors long presence in Iraq

From MSNBC:

A little-noticed civil lawsuit in Florida is shining a light on an unusual but hugely profitable Pentagon contract to ship millions of gallons of aviation fuel to U.S. bases in Iraq through the kingdom of Jordan.
The deal involves a cast of influential characters, including the king of Jordan’s brother-in-law, who is suing Harry Sargeant III, a top Florida-based fundraiser for Sen. John McCain’s presidential bid.
Sargeant is a Florida businessman and former Marine Corps pilot hailed by the McCain campaign as a “Trailblazer” for raising $100,000 or more in political donations. Through a company called International Oil Trading Co., or IOTC, Sargeant and a partner have a lucrative contract worth hundreds of millions of dollars per year to supply American military forces in Iraq with fuel, especially aviation fuel.
