Amy Walter: ‘Biggest Challenge’ for Hillary Is Voters Want a ‘Change Election’ in 2016

"I think this is just -- very quickly -- it's a changed election, OK? And I think that big driving issue in all of this is the fact that 70 plus percent of Americans say they want to go in a different direction from the president. That's the biggest challenge for Hillary Clinton whether it's on foreign policy or the economy. That's what Republicans are going to have to figure out is how to be more optimistic because I think that's what Americans are looking for, is the sense that somebody is going to come back and make us feel better about ourselves. That is going to be a driving message."
