http://nma.tv After a bruising battle, Barack Obama defeated Hillary Clinton in the Democratic primary and then went on to win the presidency in 2008. Obama coasted into the White House on a tide of popularity. However, his presidency is now on the rocks, leading voters to ask, where's the change? Many Democrats are suffering buyer's remorse. Maybe the junior Senator from Illinois just wasn't ready for the top job. Commentators are saying only one woman can save him - old foe Hillary, who has thrived in her role as Secretary of State. If Joe Biden is willing to step aside, VP Hillary might revive the lacklustre democratic base, bringing more women and union members out to vote. Other voters may also rest easier knowing there's an experienced second-in-command at hand in the face of crisis.
