It seems pretty obvious what has happened tonight.
The safer it was to send a protest to the Government, the bigger the swing.
In other words, the safer the seat, generally the bigger the swing.
Voters probably wanted to send a message to the Govt, but didn't want to kick it out.
(if that's the end result).
On the other hand, I've always believed that whoever wins the popular vote, should form the Government and I still feel the same. I've seen Federal ALP on the wrong side of that equation a few times and now this is the third time it's happened to the Liberal Party in SA.
I think that's wrong.
