It's a historic win. I don't think it's ever been this lopsided. It put it in perspective, in the space of 2x state elections, over 25% of the population moved away from making the conservatives their "primary" vote and switched to labor. Because of the win, McGowan (leader) has come out heavy on "progressive centrism". However is policies are more schools, more hospitals, slashing public transport fees, more spending on green technology, focus on local jobs etc etc.
The biggest issue for labor in policy terms has been trying to win the Legislative Council because of a ridiculous quota system heavily favouring regional and preference deals that help candidates looking for their 5 minutes of fame. It's also being predicted that Labor will win a heavy majority in the LC to basically mean they have a double majority over the government.
What this also means is that the conservative party has also officially lost their "opposition" status and how lost access to parliamentary resources like money for staff that would come from the parliament. The conservative party has essentially been wiped out in WA for the next 10-15 years.
Yes, the WA Labor party now has a upper and lower house majority over the parliament.
So our Legislative Assembly in WA is essentially the lower house, where legislation is initiated by a state government. So yes, this win is the equivalent of democrats winning 387 seats in the House (just on a state level)
Furthermore, we have a Legislative Council which is essentially for 'legislative review" there are 36 seats, Labor is predicted to win 23 seats. So in US terms, would be the equivalent of democrats holding a 63-37 majority in the senate.
No mitigating factors, the WA conservative press are running newspaper headlines of "TOTAL CONTROL" and some of their conservative TV lunatics are calling us the North Korea of Australia. It's essentially a government with a heavy government majority.
