Firstly, I know nothing about US law. For the Australian federal election this basically stopped once the election was officially “called”.

But, a printing company paid for the printing costs & volunteers (including me) put up thousands of posters, so it’s basically free. In the apparent spirit of US elections I’m sure you could charge a gazillion $ for it if you need to fit in.😀

Can’t provide data to say how effective it was or wasn’t but I can provide the anecdote that Tony lost what had been considered an unassailably safe seat. Massive swing against him. To be fair the existence of the posters were partly a reflection of that swing...

Anyway, Instagram #thinktwicewarringah
