He's definitely a control freak from what I've heard. ALPers are "taking that" (for now) because they risk getting disendorsed if they speak out against him (or any official ALP policy) or try to act against him.
That could soon change, though; I hear many within the ALP have gotten very sick of him and, using his poor polls as an excuse, will attempt to push him out a few months after the next election should he win it. Why do you think there's talk of Gillard being handed the reins?
As I said earlier, if any ALPer speaks against Rudd or his policies, they risk getting disendorsed and losing their candidacy for their seat at the next election.If the ALP didn't want the filter I would find it also very hard to believe that only 2 members would stand in the way of the rest of the party dropping it
Kate Lundy's the only Federal ALPer who's been brave enough to say she doesn't agree with the mandatory aspect of the filter. She's tried to get her colleagues to push for the filter to be optional, but Rudd and Conroy vetoed that, and Rudd gave her a major lashing for daring to speak against the filter.
