It has NEVER been about Bristol Palin. The whole thing with speculation about Bristol's pregnancy way back when came out of an Alaskan rumor justified by a few oddities in Sarah Palin's delivery of her youngest child. For me, the choices were:

Palin made a decision to fake her own pregnancy to keep her daughter's pregnancy out of the media. It would have been a strange thing to try, and so on, but would have revealed the attitudes of a mother concerned about her child, as well as a politician concerned about image.

The alternative apparently was (and apparently is), if the worst of the rumored factoids are all true,

that Governor Palin was:

1) willing to travel to Texas in the last 4-5 weeks of her pregnancy with a special needs child with potential health problems (Downs Syndrome baby);
2) after her water broke (or she "started leaking amnionic fluid"), she chose to give her speech anyway instead of going to a hospital;
3) boarded a plan knowing that she had a potential medical issue with her pregnancy while not informing the pilot so that she could
4) travel 10 hours by plane to return home and
5) didn't take advantage of the better-equipped hospital in Anchorage or
6) drive 6 miles to the better-equipped clinic closer to her final destination and instead
7) drove 45 miles to her relatively poorly equipped local clinic where she had her baby and
8) returned to work only 2 days later, rather than resting from her trip and bonding with her new special-needs infant.

In other words, we were left with deciding if she had attempted to pull a "fast one" to cover up her family's embarrassing private matters OR that she was a crazy woman.

Since she has now admitted to the same embarrassing private matter anyway, but that it is ongoing instead of taking place months ago, we are left with the impression that she is just plain crazy.

The possibility that the potential VP of the USA is "just plain crazy" is a national security matter, and NOT merely a political attack on her mother via an attack on her pregnant 17-year-old in what should be a private family matter.

It is Sarah Palin's behavior that is the issue here, either way, not her daughter's.
