Less than 24 hours after historic re-election of Barack Obama as the US President, speculation has begun here as to who would be the Democratic party nominee for the 2016 presidential elections.

The name of the Secretary of State, Hillary Clinton, has begun topping such a list along with Joe Biden, the Vice President. Notably Clinton has so far refuted all such reports of her presidential election.

"But Democrats'"and even some Republicans -- keep calling on Clinton to run, and after four successful years as the face of American diplomacy her fan base is deeper than ever.

"If Clinton were to throw her hat in the ring, she'd be considered the front-runner, just as she was when she launched her 2008 bid," the National Journal reported putting Clinton on top of such a list followed by Biden. Biden during the just concluded election campaign had thrown a hint about it.
