There are two people who really, really want to be President of the United States.
The problem is, neither one wants to run for President. Hillary has her decades-old problem with the Press. She hates them and they love to go after her. Mitt's problem is similar. It's just not the Press, but that whole 47% of us thing. I don't think he liked the crowd he had to debate with in the primaries that much either.
Both of these characters, I'll admit, would be perfectly capable Presidents. Both would make better Presidents than candidates. I would tend to favor Hillary's policies a little more than Mitt's. But then with Hillary you get Bill in the White House again. While that may be an even better two-for-one Presidency, I'm not sure Hillary would keep Bill busy enough on official duties.
I also think both of these potential presidents feel that they should be President, and both would agree that they should not have to run for it. There is a sense that Mitt wants a draft and Hillary an acclamation.
Remember that the standard for a true non-candidate is a Shermanesque, absolute statement: "If nominated, I will not run. If elected, I will not serve." Until then, they're both in the running.
I just have an odd feeling neither will be the next President of the United States.
