It's a question President Obama will surely face again and again before the next presidential election: Hillary Clinton or Vice President Joe Biden?

When faced with the question Friday of whether Obama would support either of his close allies or stay out of a possible 2016 Democratic primary altogether, White House press secretary Jay Carney insisted that Obama wasn’t giving much attention to his successor.

"The president is not thinking about 2016,” Carney said, adding that he could “guarantee” Obama had not thought about a possible Biden-Clinton slugfest.

Both Biden and Clinton have given clear signals about a possible 2016 bid for the White House. It is not yet clear whether both the vice president and former secretary of state would enter the presidential fray if the other pursued the Democratic nomination.

The questions about Obama’s allegiance came after reports that senior Obama campaign advisers considered replacing Biden with Clinton on the Democratic ticket in 2012. The White House looked to downplay such claims on Friday.

“Had anyone brought that idea to [Obama],” Carney said, “he would have laughed it out of the room."

When asked whether Biden would make a good commander in chief, Carney replied, “Sure.”

The White House press secretary said Biden’s readiness to assume the Oval Office was a major factor in Obama picking the former Delaware senator as a running mate.
