Just remember they are working the senate to ticket. This means they only need a small amount of votes to get a member into the Senate (approx 10%) ... depending on the state they represnt and number of voters etc. In other words they are.NOT contesting the Lower House and are thus not running for PM.
I say this largely due to the fact that you can vote these guys in the Senate and then still cast a vote for either one of the major parties in the Lower House.
Does this make sense to you guys and girls? It is something a LOT of voters don't understand and yet it os where our individual power lies. Just ask Pauline ...
