1 – There’s no one in the Democratic Party who possesses her abilities or her name recognition; certainly, no one who can marshal the kind of heavy hitters and money needed to pull it off. There’s no charismatic upstart to trip her up. Andrew Cuomo? Martin O’Malley? Elizabeth Warren? John Hickenlooper? Joe Biden? There’s no Barack Obama in sight. Today we learned that James Carville has joined efforts to start raising money. “He is the first of several heavy hitters who will be rolled out by Ready for Hillary PAC,” a Clinton-backer told the Washington Post. There are three other PACs already raising funds for Hillary.

2- She’s really popular. Last poll I could dig up measuring her approval rating was from Quinnipiac University earlier this year. In it, Clinton had a 61 percent approval rating among voters with a 34 percent unfavorable rating. And this survey was conducted after the Benghazi controversy. Obviously, that number deflates once partisan politics takes hold of us, but what other candidate has that kind of head start? And what kind of politician wouldn’t look at those numbers and feel embolden to run?

3 – She has to run. This is the woman who believed herself qualified to lead an effort to craft and then implement a massive overhaul of the entire health-care system, despite her complete lack of expertise or experience on such matters. This is the same women who decided to run for the Senate lacking any of the experience most people might associated with the position– most notably living in the state she allegedly represented.
