Positive, because hey, it's reform actually being proposed.
"Proposal" is a low standard to use to form an opinion. There are a lot of bad reform ideas, reducing the number of Senate seats is one of the worst. As someone who has served two terms as a regional Senator, that body needs all the active participants it can get.
Not saying it's a good idea or it should be enacted, but I have a positive opinion because, despite the flaws, it's an actual serious proposal for reform, and can of course be amended.
