While yes, Xenophon, got flogged in the lower house, he got his pretty much stock-standard 2 seats in the upper house. Whether the 2 stay aligned with SA-Best or go independent now they have no leader is another story though.
BTW your final statement I agree with. Must be a full moon tonight
It's actually interesting, in 2014 the Nick Xenophon Team was limited to 12.9% of the Legislative Council Vote whereas in 2018 it's looking like 19%.
Also interesting to note that it's Legislative Council Vote is significantly higher than it's House of Assembly (with Libs at 31.7 and ALP at 29.5).
Seems people are still pretty warm to Xenophon in the House of Review relative to government.
