Obama in 2016 if he loses
If he narrowly loses I could see him staying in the limelight, defending his policies from repeal ( like wall street and health care reform) over the next 4 years on TV which could lead to him running again. Only being 55 he'll certainly still be healthy.
All im saying is.. dont expect this guy to go away if he's defeated. Its not like Romney will have an overwhelming Mandate considering how close this election will be either way.
