POTW: Why did Rosie leave early?

So Rosie is gone from "The View" to the relief of millions of rational Americans. She was already not coming back, but leaving 3 weeks early wasn't in the cards either. After an on air dispute with Hasselbeck Rosie has decided she will take her conspiracy theories elsewhere nearly a month ahead of schedule.

The question is did Rosie leave because of problems with the cast, was she pulled by Disney for the comments she made before the show last week, or was it a combination and people just had enough of her.

Lastly, if she was a conservative would she have gotten away from as much as she managed to before she was let go?
