FILE - In this Oct. 20, 2008 file photo, then-Sen. Hillary Clinton, D-N.Y. delivers a speech supporting Democratic presidential candidate Sen. Barack Obama, D-Ill., at a rally in Orlando, Fla. A still undeclared candidate, Clinton sits atop the prospective field of Democratic presidential candidates for 2016. But as she has said before, if Clinton runs again, she'll work as hard as any underdog. Clinton's 2008 presidential bid stumbled against President Barack Obama, undermined by anti-war activists who opposed her vote to authorize the Iraq war, infighting among her staff and a large entourage in the early states where retail politics matter.
