Hillary's campaign is in the doldrums, it's going really bad, and all the pundits are saying she has to decide whether to go negative ... or negativer. I have the illusion that within the Democratic camp only, in this election cycle, going negative is hugely gonna backfire, so here's my rabbit out of the hat:

Go Positive! Even, go Positiver! And an excellent opportunity would be Michelle's so called "proud" gaffe, or rather ... O'Reilly's lynch party suggestion about that.
O'Reilly said that he wouldn't call out the lynchparty on Michelle Obama just yet, unless he found out she had a negative view of the United States! And to find that out, he would "track that down!" Does anyone hear "escaped slave manhunt"? This is using extreme KKK code here, I can hear those dogs barking right now.

Even Bush (!), just last month, unequivocally discarded the symbol of the nooze, and distanced himself from it, saying that is wasn't just a way of killing but a tool of intimidation!

Hillary could score a lot of points, by calling for O'Reillys resignation. She should go after him with a vengeance. She can go out there and state in no uncertain terms that she is outraged, (which I imagine she really is, she might just be so jaded with rightwing neonazi attack machine, it just might not register anymore).
It would be hard (and unpleasant) for Obama to do it himself, since he's so directly involved and since the current climate is such that, any defense against a racial slur is perceived as racist in itself.

So, by throwing herself on this FoKKKs grenade, Hillary would earn the respect of a lot of people. Self sacrifice is still valued a lot. She could and should make the point that she's sick and tired of these slimy, racist attacks, and that she can relate, having been in Michelle Obama position. She should make the point that on this egregious issue, she wants to close ranks with Obama. She can say that, she's old and she can take it, but that she won't stand for it being done to another Democratic First Lady.

If this would get twisted and spun into either sucking up to Obama, or signalling defeat/desparate measures/political suicide then she should shrug that off with: So f---ing what? But in more diplomatic terms, of course ;)

At worst, this will unite the Democratic party by exposing the real enemy, but at best this will make inroads for her among black women, and women in general.
Voters, and especially Democratic voters are suckers for a "everybody be friends, lovy dovey" approach, which is why Obama is so appealing in the first place.
This would affirm her aggressive persona but in a good way: That of the Mother Lion, the Lionesse
