In fact it is a screaming headline, on Page One.
And even Glen Milne (the journalist involved) can claim, as he does, that these are the conclusions from a poll done by the Labor Party, but "obtained by" the Sunday Telegraph.
Cute expression that one: not "leaked to", but "obtained by".
I suggest that you read the full article (use link above).
Howard is definitely "on the nose". While he is sneaky, and tricky, he is definitely not able to experience a "honeymoon" effect, which could just happen with Costello, should the Liberals decide to dump Howard prior to the election.
Normally they would headline this story - in tomorrow's edition. They love all this political controversy, and internecine Liberal Party politics, especially Costello stories (they usually refer to him as "The Smirk").
But the article is written by Glen Milne, who is memorable for his "apparent assault" on Crikey's founder Stephen Mayne, at a televised Walkey Awards ceremony earlier in the year - on account of Milne's obvious dissatisfaction with Mayne's entitlement to the award he was given. The link above takes you to the Age's report of the Awards, and photo and discussion of the "incident".

How forgiving is Stephen Mayne? We shall see tomorrow.
