In 1990 a candidate in Tacoma WA ran for US Congress from the left in the Democratic Primary against a well funded entrench DINO opponent. In the midst of that race being out funded by a wide margin he did the only thing that he could do that was with in his price range (internet had not yet come into widespread use) he put up yard signs in violation lof the city/s 60 day time limit.
A few days after he that, the city came to people's doors and told them to get the sign off their lawn or out of their window or else they would be fined or in extreme cases criminally charge.
The case went to court and Collier won that case 9-0 the reason being that political speech had to be protected before all other speech ie (religious, commercial etc) and the secondary reason being that the city and it's workers could not define what was or was not a political sign depending on the message.
The court did rule that that the city could "reasonably" limit size and also keep them from being a safety hazard.
The court also rules that this was the case for right of way, HOA's etc.
