Hillary Clinton's popularity has soared since her bruising campaign against Obama, and she would begin the 2016 nomination contest as a heavy favorite if she were to pursue it.

"He knows how to make the case. I've seen him make the case even when he doesn't have much to work with. He has a lot to work with," Ickes said. "He made a very powerful case for re-election."
