Look for McCain to do very well in Northern, VA and East of I 95. Western Va is up for grabs, but as a winner take all state, McCain should handily win the VA delegates. Look for McCain to also score well in MD and DC. My guess is that Huckabee wins Western Maryland (where I'm from), as well as the Eastern Shore. Still, the population areas of Maryland will probably go for McCain. 100 delegates today is not far fetched.
My guess is that Obama wins big in VA, DC, and MD. This is anecdotal, but I can tell you that when I voted, all the energy and supporters were for Obama. I suppose Hillary has a chance in VA, but my guess is it's all Obama today.
