Ah. It's a bit more clear why the Detroit News opined against 10% plans.

According to the Michigan Daily, Rep. Rick Jones (R-Grand Ledge) proposed it in legislation recently. His idea, while I understand it is well-motivated, is misguided. MCRI's goal was never to dictate exactly how universities would respond - only to set the guidelines. Let's allow universities some time and flexibility in their response and see where that puts us before adopting anything like this.

Send Jones a (polite) note opposing this proposal at this time.
