How often do you have to repeat an unsupported allegation before it's accepted? Many times.

That seems to be the hope of Labor backbencher Justine Elliot who has launched a social media campaign claiming that the Morrison government plans to introduce a cashless welfare card for pensioners.

The MP For Richmond told her Facebook followers: “If reelected, Scott Morrison will force pensioners on to the cashless welfare card. The plan will put 80% of your pension on a card that will limit what and where you can spend your own money.”
