One final anecdote from that Newsweek series:
The day of the third debate, Palin refused to go onstage with New Hampshire GOP Sen. John Sununu and Jeb Bradley, a New Hampshire congressman running for the Senate, because they were pro-choice and because Bradley opposed drilling in Alaska. The McCain campaign ordered her onstage at the next campaign stop, but she refused to acknowledge the two Republican candidates standing behind her.
