It makes sense for the Democrats, actually. Clinton has done an incredible job as secretary of state. First of all, she has worked harder than anyone should ever be expected to. She has managed to do the impossible: She is the ambassador of the United States to the world, maintaining her credibility while playing the bad guy to President Obama’s good guy, such as with North Korea, Iran and Israel, and still looking good. She has been a true team player. If Clinton is dissatisfied with her role, you would never know it. She has been loyal and supportive to the president and has maintained a good relationship with him and with others in the White House. If she is being left out of the policymaking, or being sent on trips to keep her out of town, she has not shown it. She is cheerful, thoughtful, serious and diligent. There are no horror stories about her coming out of the State Department. Most notable, though, is that Bill Clinton has not been the problem that so many anticipated. He has been supportive of her and of Obama, and he has stayed out of the limelight and been discreet about his own life.
In short, the arguments against Hillary Clinton being Obama’s vice president have pretty much evaporated.
