I don't know that Hillary has had to put up with crap to the same extent that Palin has already......
Hillary was a known politician on the national and even world level. People know her background and she's been through the media circus in the past.. How easy it is, for you to forget all the crap the right wing give her fore staying with Bill when he was caught having a affair. All the crap she was given on her way up.
Palin is exactly what happens you you make someone your VP pick who is relatively unknown and has very little experience. If she had no dirty past, then the media would have been in a frenzy for a week or so then it would have cooled off. However every time you turn around there is more dirt under the rug with this woman. This is the exact reason you don't bring a politically unknown into a major campaign as your running mate.
In short, because McCain didn't properly vest her, the media is doing it for him. That was his choice and had he done his job of fully checking her out rather than jumping into this mess last min, well then things would be a bit different because he likely wouldn't have picked her.
