If Angus Taylor is ever to be PM and put his mainly-pinched-from-One Nation immigration policy into practice, he will have to deal with the wets who will stab him in the back as they have done to even mildly conservative leaders in the past.

Onesuch is Senator Andrew McLachlan, completely unknown to most South Australians and probably all other Australians.

This person got into the Senate just by being on the Liberal ticket years ago. He has done nothing. Said nothing, until recently when he voiced objection to the term 'mass immigration'.

Now, he has come out in direct opposition to his leader's intent to block NDIS and 17 other welfare payments to non-citizens.

He bleats the usual crap about non-citizens paying taxes etc. They pay taxes because that's the law. It doesn't make them saints.

Anyone who wants to live here permanently, but doesn't want to become a citizen is automatically suspect.

McLachlan told the ABC, that great friend of his party, that he has been in the Liberal Party for too long. That's probably the truest thing that he has said in his miserable career.
