You will vote for who our forefathers told you to vote for. The shooftee ol buggers set it up like that, so all their descendents from their ilk would remain in power.
Its called the "preferential voting system."
Just because you vote for candidate X does not mean that first past the post wins. Two others contesting may share their preferences and thus may, combined, out poll your candidate you can well end up with some dropkick you don?t want.
Take Greens and Labour, most times they share preferences. This gives one a leg up, so a conservative contesting may not get in, even if he is first past the post (has most singular votes)
Same for Libs Nats/Country
Clive Palmer?s mob are a typical group saying they are the answer. And on first look they may well be, but most it?s a bloody big con, as they will share preferences to allow one of the like minded group to out manoeuvre a strong single contestant.
An independent is one out of the box, usually well liked in his/her community. They , once elected, then play the preference game to stay in a seat Nothing wrong with that play, as its legal, but hard to shift once they are in.
