It's definitely a mistake to think that the scandals that have dogged Hillary Clinton over the past few weeks will have any impact on her future, or her intended coronation. She's a Clinton, after all, and Clintons are immune from the ill effects of bad policy, bad press and bad ideas. And if they're not, they'll throw around some decorative accessories until things go their way - or the aide assigned to tell them the bad news has the kind of amnesia-inducing concussion that people only get in soap operas.
But it seems that, at least privately, Hillary's most obvious challengers are considering whether they have the foundation to mount a challenge. This week, as Hillary Clinton bunkered up and Bill Clinton flouted his bank account, Elizabeth Warren just happned to pow-wow with some of her most ardent progressive supporters, who just happened to also be the masterminds behind the Draft Warren movement.
