In March, when Obama was still very popular, she and her father opposed him on "torture," Guantanamo Bay, and other security issues, and sent "The One" packing. By summer, she was on so many news shows that liberal bloggers attacked the programmers who gave her exposure. This is the sign she was being effective. If she were hurting her cause (or her father) they'd want her on air all the time.
Wolff (and Maureen Dowd) try to damn her by saying she's part of some dark Cheney enterprise, but the reason they loathe her isn't dear dad. She's what they fear most, a rock star with outreach, a feminine woman who isn't a feminist, a conviction politician who crosses culture lines easily, and isn't easily set up or mocked.
