To add some nuance to this most people vote by party in the senate.

I think this is more fair for senators than lower house. Senators represent their whole state, while MLAs represent their local electorate. I can see scenarios where the needs and wishes of your local electorate are not quite aligned with your party on all issues and in those situations, you should do what your electorate would wish of you.

This is a really murky issue for any senator. The YouGov polls show wider support for a Palestinian state than the Government does. But it also shows that more of us are unsure on this topic than those who support/don't support. Which stands to reason, the region is really far away from us and we aren't all that involved, really.

The pessimist in me dismisses much of the government's position on the conflict as aligning with US interests. Which takes us back to Senator Payman. On this particular topic, I believe her firm position probably both is representative of a decent slice of her state as well as being a foil on the generic support of all things US from her party. Good on her.

I'm not really into party politics, so I don't really have a stake in whether she should be ejected from her party for this. But if pressed, I'd say they'd be making a mistake to eject her over this matter. This is not a major party policy, and its position does not have wide-spread community support.
