I post one of my intervention in the Senate thread bill. If the problem is presentation of the census I suggest of finding other ways to present census, maybe put the bigger parties in a table and the others separately. I'm Chair of a small party and this bill will make it harder to be visible and survive.
I am strongly opposed to increasing the number of members required for an organized party. You should not make it harder for small parties to be visible to give them a chance to grow. Or only because a few people should have a party they believe in, and respecting political divversity.
Not sure if it's the formating in the census that is causing problems (too many columns). If it's that maybe it would be acceptable to list the smallest parties below the table, just one line by party. Like
SOS party 2-0-1
XYZ party 0-0-3 (numbers are members for the three regions).
Or even if it respects the requirements, just for the smallest parties list only the number of members below the table so the public knows they exist.
SOS party 3
XYZ party 3
The problem we have is mammoth parties, it's not the tiny parties so maybe try to find ways to accomodate the RG without changing a longstanding rule of our democracy.
