Here is a new one, allegedly with bipartisan support, which makes me suspicious....
"Labor will introduce a bill to parliament on Monday to change electoral laws, with caps on donations and campaign spending."
(From ABC news)
Sounds great in theory.
But it only limits Party and Candidate donations and spending.
The USA has PAC system whereby an arms length organisation gathers money to pay for advertising, and not being part of the party, choose to pay for their own advertising to 'help' someone to get elected.
And no lifetime limit for candidates.
