It belabors the obvious to point out that four years ago almost any American would have bet on the likelihood of hellfire in the Arctic Circle over the probability of an African-American being a major party nominee for president of the United States. And, somehow or other, Barack Obama managed the feat without name recognition, a fundraising network, and virtually no national connections. Obama does have charisma, vision, an agile intellect, and superior political mind. A woman candidate with these credentials will be formidable indeed, even if we don't know at the moment who she might be. If nothing else, Barack Obama has proven that a genuine political force can come out of nowhere and dominate the political scene.
In truth, the "next" woman candidate (and who is to say that there won't be more than one?) doesn't have to be the second coming of Barack Obama to be a better candidate than Hillary Clinton. After all, Clinton's name recognition, fundraising, and connections result from being the spouse of a popular president. Her successors will achieve what they achieve on the basis of their own abilities. They may not be so lucky, but my guess is that they'll be better.
