For any Aussies: What will be the effect of not having a majority in the Senate? Will the Carbon tax repeal have difficulty?
On the Senate question, we won't know exact Senate results for some time, but on current indications the Coalition will have 33 Senators, which is not enough to command control of the Senate in its own right.
But, it looks like the Palmer United Party will have two Senators, and Senator Nick Xenophon (an independent) will be returned. These three will almost certainly support the coalition on most issues, getting us to 36. Family First may have also returned a Senator, and again on most issues, they will support us. That's 37. And if the Democratic Labor Party take another seat (and that looks possible), and they support us as well (despite their name, they share a lot of common ground with the conservatives) then with the one they already have it's 39. The Senate has 76 members, so 39 is a majority.
In other words, if things break our way, we should be able to get our legislation through the Senate with the support of minor parties. Labor and the Greens together (our main opposition) look like that will only have 35. We might even pick up one or two more above the 39.
It's looking OK at the moment - we'd prefer control in our own right, but we do have high hopes it'll be workable.
