You're probably right, she'll coast to Senate re-election in NY. But it'd be fun to see her relentlessly attacked from the left in the meantime. The moveon.org crowd is determined to promote the most radical leftist they can get for president, and Hillary is going to have to be pretty nimble, as it stands now, to get their support. Ought to be great to watch.
Moveon will back hillary, granted she's not Lenin or Mao, but she's the next best thing.
That's exactly what she wants. She's running to the middle. If she gets attacked from the left almost as badly as she will be certainly from the right, she looks exactly like the "above-it-all" centrist that she's trying to pose as.
Attacks from the left are designed to make people think she is center or right. This is all staged.
