Of course, such concerns never seem to deter the Clintons. It's all about winning, no matter what the cost. Obama better concentrate on putting her away convincingly between now and then, which will be easier said than done when you consider the possible reasons for Hillary's turnaround.
It could simply be that she was always supposed to win those states and she managed to hang on. But even there, she couldn't have done so without holding back the Obama tidal wave, which she did.
At any rate, it seems she either convinced voters that Obama really doesn't yet have the experience or gravitas to handle that 3 a.m. crisis call or that he actually does have weaknesses (NAFTA-gate, Rezko, etc.) and thus isn't a god after all. And don't forget the urging of a certain shrewd talk-show host that Republican voters cross over for Hillary.
Since exit polls show that voters who decided in the last three days went Hillary's way by an almost 2-to-1 margin, it's safe to infer that whatever other factors were at play, Hillary's negative campaigning worked. Thus we can be sure of more of the same in the coming weeks, which will present Obama with a dilemma of his own.
How will he be able to fend off Hillary's attacks without going negative himself? And if he gets down in the dirt with her, does he not betray his promise to remain above the fray as a uniter? Gods don't get dirty.
Meanwhile, if Hillary also continues to play up the theme that Obama isn't ready for that 3 a.m. call, and Barack fights back on that turf, they will both be playing into John McCain's hands because the 3 a.m. call has to do with national security.
All of which is to say that though most polls show either Obama or Hillary defeating McCain in November, Democrats have their hands full, and they are guaranteed to get fuller. This should be fun to watch.
