voters prefer rudd and turnbull as leaders, page-7

why did the pollsters include the former rudd and turnbull in their polls...were they stirring things up, spurious reasons to ask the questions....
anyway they blew themselves up...with Abbott a whopping 19 points above turnbull as preferred leader amongst liberal supporters.....thats a wipeout in my view.....abott is way in front....

hint, spurious response here I believe....labor supporters prefer tunbull....cause turnbull is recognised widely as a labor man, not liberal....
and liberal supporters playing games, by suggesting rudd is preferred to gillard....

extract only......
In a closely parallel result, 23 per cent preferred Joe Hockey as Liberal leader, 31 per cent Tony Abbott and 37 per cent Malcolm Turnbull. Among Liberal voters, however, Abbott was preferred over Turnbull by a margin of 19 percentage points.

ps all these polls .....what did the last election actually do...the polls showed labor at 38 with greens 12 in august 2010....the coalition at 44...since then the coalition has increased to 45, labor decreased to 33...and the greens are unchanged....
