(CNN) - Barack Obama's campaign immediately highlighted a singular moment in Tuesday's presidential debate when John McCain sought to criticize Barack Obama for supporting the 2007 Bush-Cheney energy bill:
"It was an energy bill on the floor of the Senate, loaded down with goodies, billions for the oil companies, and it was sponsored by Bush and Cheney," McCain said. "You know who voted for it? You might never know. That one. You know who voted against it? Me."
Obama campaign spokesman Bill Burton immediately emailed reporters noting McCain's seemingly peculiar reference to the Illinois senator.
"Did John McCain just refer to Obama as 'that one?' Burton asked.
