I think he has been stabbed in the back by his closest team mambers - Gillard and Swan. Yes he was suported by them to become the leader. But he was put up there because of his "personality" to get votes and win the election, which he did........but also in great part due to the stubborness of Howard.
Once he is in.......he runs it as "my house my rules".......but he always did things through his "kitchen cabinet" of Rudd Gillard Swan Tanner.
If things turned sour, which it did, it was not just Rudd's fault. It was the fault of those 4 making the decisions without consultation. If Gillard and Swan were looking out for him, they would have insisted things go to the caucus and party rather than make the decisions within the 4 of them.
Does everyone remember Mark Latham....very popular until his true colours turned up. Lucky he did not become PM before everyting was all found out. Unfortuantely for us, Rudd's true face came out after he got the top job. No one knew of his mean streak before he was elected.
