@dadpad,
A number of polls have indicated that significant numbers of voters are disenchanted with
both the Labor & Liberal leaderships & also with their parties' respective policies .... & that voters are looking for alternatives.
Whether the strong showing of say,
the Greens in the recent polls will translate into actual votes or not, well, who knows? However, Labor under Rudd, has definitely lost credibility with left-leaning voters, conservationists, people who favour more humane treatment of refugees & also left unionists, amongst others. Whether changing to Julia Gillard at this late stage (if it happens) convinces many of the disenchanted Labor defectors to return to the fold, it's hard to know. As I said earlier, Julia Gillard appears to be very closely allied to the "Rudd line", so I'm wondering if the perception of
what Labor stands for will actually change a great deal as a result of a change of leader. Hard to know.
