Clause 5 is enough to send red flags alone.
Yeah, I also have concerns about Clauses 3 and 5. What constitutes "coercion or intimidation?" Is it intimidation to send three private messages? I'm the chairman of a political party, so I sort of have an interest in mounting aggressive, hard-fought campaigns. I'd like to know that I'm in the clear.
Also, what counts as "interference on the basis of candidate preference?" Sorry, but I plan on telling voters exactly who I think should have their first preferences. In certain cases, I may even have something to say about their second preferences, too. That's protected in my constitutional free speech rights, is it not? Maybe I'm misinterpreting what you meant, but if that's the case, I think we should probably clarify that clause.
