When asked if he regrets voting in favor of the invasion of Iraq, John McCain justified his vote by wondering what Saddam Hussein would be doing with the profits Iraq would be making of a $130 a barrel oil. He would be buying Ferraris armed with ICBMs, that's what he'd be doing!
Of course, if we never invaded Iraq, creating Middle Eastern and global instability, oil prices never would've shot up so high in the first place, but if you're planning on voting for McCain, you probably didn't think that far down the line. Don't feel bad. McCain didn't either because he honestly has no idea how cause and effect works.
