Mr Windsor’s primary vote is tracking at around 44 per cent.
Mr Joyce told media in Tamworth this evening that he had faith in the bookies’ predictions that the Coalition would win.
“In the seat of New England I think the bookies are right again,” he said.
“The National party will hold that seat.”
Throughout the campaign, Mr Joyce has maintained he is “confident, not cocky” about his chances of beating his arch rival, the independent candidate, Tony Windsor.
But this morning Mr Windsor said he was confident he would win.
The two men have been locked in a fierce and bitter eight-week campaign, complete with attack ads and nasty stories appearing in the media.
This evening a sign was stuck to Mr Windsor’s campaign office door which read, “No access to News Limited Media”.
When asked by the ABC’s Leigh Sales why he would post such a sign on his door, he replied he did not want News Corp there and that his team “pay the rent” for the building.
Earlier this week the Australian newspaper published an article alleging that Mr Windsor had bullied and whipped school mates at an agricultural high school in north-west New South Wales.
Mr Windsor said at the time he would not respond to the “gutter journalism in the Australian” and he has referred the article to his legal advisers.
Media player: “Space” to play, “M” to mute, “left” and “right” to seek.
