I would always say at this point, because the numbers required to achieve parity are so small, that individual-level barriers are not the problem. This means that we actually have to have an institutional solution. I've spoken with Jeannette Ashe, who is a research colleague of mine in another institution, and I believe it's similar to this particular bill that you've mentioned.
I would support penalizing parties on their election reimbursements if they cannot field parity slates. As we know, a great deal of political parties' election-based financing comes from campaign reimbursements. You spend a certain amount, and then you can get 80% of it back. That should be, in my view, docked depending on how few women or visible minorities a party fields. Something tells me that if you tie diversity to the money, parties will solve the problem overnight. They just will.
