i think even the people who thought she was genuinely scared etc.. still voted for her.
on one side leaving is simply because she's had enough she doesn't want to be a national joke anymore, why stay in? for her kid(s)? dont know how old they are, if they're babies, they wont know about it, and when and if they're old enough, i'm sure they get enough crap from other kids for it, or so much time will have passed to care.
according to her, the public made their mind up, there aren't that many fans of hers - really its the first sensible thing she's done by leaving.. would have been terribly sensible if she left on the first night when she mentioned the idea (cue the attention and ego boosting), and well every single day since then.
as Fleur said, sympathy if it was the first series, but otherwise no cookie.
