Its fairly accurate at first glance. It reflects events in Maine, Iowa, Minnisota, Nevada, Colorado. We may have swept Nevada, but 20 are still technically bound to Romney.
The only inaccuracy that I see time and again is Florida, Arizona, New Hampshire, South Carolina, and Michigan were all penalized 50% of their delegates. That eliminates about another 50 delegates from Romney, and isn't reflected on that page.
