Yeah, ok so I read up a bit on it in the Guardian, which reflects the points you made there.
I guess we won't know anything for a while by the sound of it, but the options then are
Labor gunning hard and getting lucky
Bob Day clone or Bob Day not-clone
Someone from Kenya we know nothing about
Also, who knew Family First were organised enough to have factions? I assumed that apart from being a front for that happy-clapper church that Fielding belonged to, they had very little game. And I still incline to that view, that outside of their fundy concerns they probably have a pile of Amway/Prosperity-Gospel baggage and thus are proxy Coalition supporters. But still, as One Nation learned back in the day, and Clive Palmer United more recently, there's nothing to rule out a total wildcard who just joined because putting families first sounded like something they might be in favour of, and are otherwise completely outside the party's tent.
PS apologies for the brevity of my response last night but it was basically midnight and off to bed for me, and today isn't much better busy-ness-wise! Much as I'd love to join the scintillating discussion with Bob Saget and Deep over at FYM, I just can't spare the moisture.
