The jockeying for the 2016 Democratic presidential nomination is already shaping up to be nothing like the 2008 contest. Indeed, it doesn't even resemble a contest. It's not going too far out on a limb to say that, unlike six years ago, the nomination is Hillary Clinton's for the taking, if she wants it.

This will inevitably lead to the idea of her inevitability — and there are few words in politics more despised than that one.

Presidential aspirants have a love-hate relationship with that word when it's attached to them.
