In this photo taken Dec. 3, 2014, former Secretary of State Hillary Rodham Clinton speak at Georgetown University in Washington. In 2002, then-Sen. Clinton took a vote in favor of the Iraq war that would come to haunt her presidential prospects. Now, a new generation of senators weighing White House bids _ Marco Rubio, Rand Paul and Ted Cruz _ will have to make a similar choice about President Barack Obama’s use of force request. Clinton, too, will face questions about her position on Obama’s proposal, but this time has the advantage of avoiding an actual vote on the Senate floor. (AP Photo/Carolyn Kaster)
