Democratic Debate minutes away

It starts in ten minutes. Hillary has two choices. Well, three actually.

1. Stick to the issues.
2. Go massively negative.
3. Start nice, go negative about halfway through, then get nice again for the last half.

I suspect Hillary will take option 3, which she's done before (including the last debate). Hillary has to rattle Obama, or the nomination is over - he's won. It is unlikely that she'll get 65% of the vote in Ohio and Texas, which she needs to get the nomination, so she has to get Obama to screw up. And the best way to do that is to rattle him, by going negative. But, if Hillary goes negative, then she looks bad - she doesn't do negative well. So, she may choose to start positive, go negative halfway through, to see if she can provoke a reaction, then go positive again for the last part so people lose any ill-will that may have been generated by her turning negative.

The thing is, Obama knows this. I'm sure his people have told him that under no circumstances is he to take the bait. If he doesn't take the bait, he wins. What option will Hillary choose? We'll find out in a few minutes.
