West Australian Liberal MP Andrew Hastie has blasted the Coalition's election campaign as being out of touch and for alienating grassroots members.

Prime Minister Malcolm Turnbull said yesterday he took full responsibility for the party's performance in the election and said it showed there was a "level of disillusionment with politics" that all parties needed to address.

But that acknowledgement has not stopped internal critics, with Mr Hastie the latest to add his voice to the chorus of complaints.

He told a local newspaper he threw aside the Coalition's talking points on jobs, growth and innovation when he struggled to tell a constituent how the plan would benefit his children.

"I struggled to answer," Mr Hastie said.

"It was at that point I realised that a lot of what we were campaigning on nationally just wasn't resonating with everyday Australians.

"He couldn't understand the reason for company tax cuts, he wasn't earning enough to benefit from the increased tax thresholds and he wasn't an innovator — he was just an everyday Australian who was trying to pay down his mortgage and look after his children and ensure they had a brighter future."

'I basically ran my own show'

The Perth-based MP said there was "kick-back" from rank-and-file members angry about the Coalition's proposed changes to superannuation.

He took aim at campaign strategist Mark Textor, saying there was a disconnect between campaign headquarters and what was happening on the ground.

"Look, I can't speak for Mark Textor, but I'd love to ask him if he's ever been to Canning and spoken to one of my electors because certainly there was a disconnect between the campaign nationally and what I did on the ground and I essentially ran my own show," he said.

"I did the political field work — I went out and knocked doors and spoke to as many people as I could and the more I did that the more of a disconnect I sensed between the voters and what we were campaigning on."

Mr Hastie's Liberal colleague Senator Cory Bernardi has also criticised Mr Textor, who last year declared "conservatives don't matter".

Writing in his weekly newsletter, the conservative South Australian senator said the campaign result was a disaster and was in part because of in-fighting and his party's decision to topple a first-term prime minister.

"In my youth I was told that the definition of madness was doing the same thing over and over and expecting a different result," he said.

"That axiom has borne out once again."

Senator Bernardi repeated his concerns that the Coalition's vote had been splintered by minor parties and said it was clear that voters do not believe either side of politics was doing a good enough job.
