Strategically, this isn't a smart move on the part of the Democrats. She is a lightning rod for two reasons: 1) she's a Clinton; 2) she's a woman. This latter might sound harsh but I don't think the general electorate (i.e., the average American) is ready for a woman president. And you might counter with "well, perhaps they weren't ready for a black man, but look at Obama" to which I would counter with "see my point #1". Folks with even marginal anti-Democrat tendencies or undecided voters with slight Libertarian leanings will not be on her side. And there is a huge amount of sexism in the USA, the same way there is a huge amount of racism. Obama won the presidency with a large percentage of youth voters--many of them were first-time voters, with unmarried women making up the largest percentage of first-time voters. I'm not so sure Hilary will galvanize that same demographic. Overall, doesn't seem smart on the part of the DNC.
And to be clear, I would easily vote for Hillary and have no problem with a woman as president. But more important to me is keeping tea-party and/or Republican folks out of office, with whom I profoundly disagree (the latter is a huge understatement). And strategically I'm not so sure Hillary is the right person to do this.
I will happily eat crow--gleeful mouthfuls of it--if she is elected in 2016.
