I think people like her because of her "JOURNEY" (ach nein the J word!)
I am not voting for her, I don't mind her too much though. I do think her crying has become a bit annoying. I am all for letting it all out, believe me, and having a few tears because of a really bad score or crying because you were in the dance off for the first time, that's fine. But now it's become crying because she gets GOOD scores, and crying because people DO like her. She should just try and smile a bit more ... nothing against her, but people were complaining about Rachel crying her eyes out when she was in the dance off. She had tears once on her VT. Now Lisa has become the crying queen and it seems to be "OK" because she has had "such a hard time". Her sisters are also really annoying...all this going on about seeing someone they love in so much pain, and how they have her crying on the phone, and how its hard to see someone they love suffering SO MUCH...come on now, she's not dying or anything.
Having said that, I can see where some people find the attraction in her and her "story". Just in the past couple of weeks she has become a bit of a moaning minnie. No offense to any of her fans.
