The federal government is on the nose because of difficulties communicating its message and a fractious parliament, says former prime minister Kevin Rudd.
Asked why Labor was "on the nose", Mr Rudd blamed communication, and the unusual parliament.
"There are difficulties of communicating a message," Mr Rudd told Fairfax Radio on Thursday.
"The core of the government's challenge is dealing with a very fractious parliament."
Asked whether he would allow himself to be drafted as leader, Mr Rudd said he supported the prime minister.
"I said I won't challenge, I mean that," Mr Rudd said.
"The issue of a draft doesn't arise."
A recent Nielsen poll put Labor's primary vote at just 30 per cent, down five points since December.
Mr Rudd said there was a lack of historical context in poll analysis, as former prime ministers John Howard and Bob Hawke had faced sagging popularity at some point.
"These are difficult times," he said.
"Of course the challenges are real. Our challenge is to explain our record."
