Despite all the positive news 2013 brought former Secretary of State Hillary Clinton, an interesting theory construed by Washington Post puzzlement columnist Richard Cohen:

 A good politician, as Napoleon once said about military men, has to have luck — and this has not been a lucky year for Clinton. If she’s the next Democratic presidential candidate, she will have to follow a Democratic president whose approval ratings — once as high as 76 percent — are now scraping 40. As a former member of Barack Obama’s Cabinet, she has to defend the indefensible, kiss the ugly baby of Obamacare and smile for the cameras. She can do it — no one soldiers on better — but ugly is ugly, and the rollout of Obamacare has been just that. …

Hillary Clinton … is the quintessential Washington insider, a former secretary of state whose portfolio is devoid of a soaring triumph and whose name is attached not to some diplomatic doctrine but to a failed health-insurance plan. She might make a wonderful president, but she’s following a man who, by virtue of his failures, has made that harder. As in 2008, Barack Obama could wind up defeating her.
