Here is her resignation letter.

She doesn't come off as opportunistic or spiteful. It seems like she is someone who was convinced to run rather than someone who wants to make a career of it. Her stepping down means a lot more than Len Webber.
Also of note is that she wasn't one of the ten who met last night. She seems to be stepping down simply because she doesn't want to be associated with the PC leadership right now.
