In this most fascinating and lengthy of Democratic primary races, it is that time again for Hillary--should she lose both Indiana and North Carolina today, she will find herself in a position where she probably needs to get out of the race. Or even if she splits close contests. It's unlikely, but possible, that she may also win both states, if Jeremiah Wright has hurt Obama as badly as many polls suggest he has.
The race has definitely been getting dirtier. There has been some scandal among Obama supporters about Hillary's pushpolling techniques in North Carolina, although they haven't yet stooped to the level of those used against John McCain by Karl Rove in 2000 in South Carolina. What is a little scarier is that a pro-Hillary group called Women's Voices Women's Votes has supposedly been robocalling black North Carolina voters and telling them their registration packets are in the mail, thus confusing many who have already registered.
In my opinion, at this point in time, despite or because of these (historically-speaking) rather tame dirty tricks, Hillary is making a strong case that she will be the better candidate against John McCain this fall. This is simply because she responds to aggression far better than Obama does. This is not about who would make the better president--a point I make over and over again is that you can do a lot of nasty things during presidential campaigns and still become a very good chief executive-- but simply about which Democratic candidate would have the best chance of winning in the fall. Of late, anyway, that would be Hillary.
