For me it would be the proportionality. It would be how the seats are divided up and who actually sits in those seats. If you capture a certain amount of the popular vote, that translates into a certain number of seats. That's not what currently happens. Right now we see a really disproportionate piece. There's a huge majority in our House right now. That's not what the popular vote reflects.
