As SHOCKING as THIS is the ENTIRE NorthEast is RINO Central.
I must also note that Governor Palin is famous for saying, "Don't Retreat, Reload." I think that the Tuscon thing is a reminder of this pugnacity worthy of the Minbari Warrior Caste.
It has occurred to me that Sarah Palin has the attitude that George Washington and Ronald Reagan had towards power-- they didn't really "need" it. But they would serve if they thought that the nation required it. Thus, if Sarah Palin can help someone else who shares her values and priorities become POTUS, then that is fine by her. But if she has to do it herself, then she will try to do so. I think that her political biography shows this from the local PTA to the 2008 campaign.
What I fear may deter her from running for the Presidency are the very real threats to her own personal safety and that of her family. If anyone is concerned about the level of death threats against Mr. Obama, then they should get ready for some really kooky action.
