Third debate takes Obama, Romney away from domestic energy fight

The third and final debate between President Barack Obama and challenger Mitt Romney on Monday night is being billed as a foreign policy discussion, which seems natural to cause a tussle over global oil supplies and U.S. foreign oil dependence.

But with Romney focused in recent days on the attack on the U.S. consulate in  Benghazi, Libya, and Obama ready to tout his record of ending the wars in Iran and Afghanistan and killing of Osama bin Laden, watch for energy to play at best a supporting role to bigger arguments.
