Political speech has stronger 1A protection than commercial speech and one could argue for a ‘fair use’ exemption. Strong enough to win on its merits? I don’t know – I’m not an IP lawyer, probably not. Strong enough that a well-funded legal team could get a federal judge, hesitant to make a ruling certain to be criticized as ‘election interference,’ to delay a decision until after the election when the signs are all being taken down anyway? I think so.
Clearing both lower ports from a sitting position isn’t a problem. The problem is when one feels simultaneous urges to defecate and vomit. I’m fortunate enough for this to be a rare occurrence personally, but I do keep a mop bucket within reach of the toilet.
