Fake nice? It's possible.

I never met Herzog, but by all accounts she seems genuinely charming. People crawl out of the woodworks to support her. If people even did that for über-bully and career destroyer Lance Armstrong, you can imagine how deep that might stick with fans of a charming skinny brunette. I think she's not evil as some say, I think she's in dire need of help for personal issues. Can't make it to a large track tournament on doping living at altitude. What'is she trying to prove to whom? Get a job girl, run for joy!
