President Obama said both Vice President Joe Biden and former Secretary of State Hillary Clinton had done an “incredible” job in his administration, but he was focused on governing and not looking ahead to the race for the 2016 Democratic nomination.

“What I would say to folks out there is we are tremendously lucky to have an incredible former Secretary of State, who couldn’t have served me better, and an incredible vice president who couldn’t be serving me better,” said Obama in an interview aired Sunday on ABC’s “This Week.”

The president said it was “premature” to start talking about the 2016 race.

“I just got reelected last year. My focus is on the American people right now. I’ll let you guys worry about the politics,” said Obama.

Clinton has not said if she will run in 2016, but polls show her as the runaway favorite for the Democratic nomination. Many of her supporters are backing the pro-Clinton super-PAC Ready for Hillary in expectation of a potential bid.

Biden has declined to close the door on 2016 and is slated to speak at a Democratic fundraiser in Iowa Sunday.

Biden is speaking at Sen. Tom Harkin’s, D-Iowa, steak fry, a key stop for presidential contenders. The vice president also visited Iowa in January and stopped in South Carolina in May, fueling speculation about his political future.
