Below is the one I just sent in. It's probably too long and I bet you're correct that the second part is too pointed for someone like Larry King to ask - in fact, I wouldn't be surprised if King has already agreed to stick to a list of questions provided by Chavez.
"How has nationalizing foreign investments helped create jobs and further investment for the people of Venezuela and does Mr. Chavez intend to nationalize the Las Cristinas project, taking it away from Crystallex of Canada that has invested so much into the surrounding communities such as hospitals, water treatment facilities, roads, etc.?"
