I am not sure that they threw anyone under the bus! I remember the conversation as a constructive one where both agreed that the gay couples deserve the same right as heterosexual couples. The only exception is that they did not want gays to claim the word marriage. In the age of advocating moderate stands on many issues and keeping an open mind to ones surrounding, I don’t see this approach as negative. I think we all agree that we need to be sensitive to the other side’s views. The right is sensitive to the word marriage, then let's not call that, if gay couples were to get all the right that are associated with that word.

As far as Ms. Palin calling for the amendment, this is becoming a trend. She speaks out about an issue, a day or two later, she corrects the record, or make a clarification that speaks against her initial views. Examples:
1) Gay couples rights… later the amendment
2) Against robo-calls initially, later recording one herself
3) Etc, (I need to come up with the third one to make it a trend, but can’t remember, therefore you get the generic etc. )
The trend is clear; her initial logical instincts sometimes are on the right place, later to be derailed by her handlers.
