In Arizona, I've found ophthalmologists to be the most politically involved MD specialty. US Senator Rand Paul is an ophthalmologist. I see an ophthalmologist yearly in Flagstaff. He flies the same aircraft I fly and he is ON THE BALL politically. They are relatively small in number (200-300 in AZ), but man are they SMART and vocal and know what's going on. If you need a doc to operate on your eyeball(s), he'd better be sharp!
