Obama: If I ran again, I could win

In urging African leaders to share power and recognize the value of changes in government, President Obama used his own term-limited tenure as an example on Tuesday -- and made an interesting comment about 2016.

"Under our Constitution, I cannot run again," Obama said in a speech to the African Union in Ethiopia.

He then added: "I actually think I'm a pretty good president -- I think if I ran, I could win. But I can't."

And that's a good thing, Obama said, because "I know someone with fresh blood, new insights will be good for my country."

As for himself, Obama told the African leaders he can still serve his country after leaving office, as well as see his family more often and travel without such a large security entourage.

"I'm looking forward to life after being president," Obama said.

The speech capped Obama's trip to Kenya and Ethiopia. The president flies back to Washington on Tuesday.
