Who do you think should be among Dallas' most powerful?

Each year, I have the opportunity to name the ten most powerful people in Dallas for Yahoo News. To compile the list, I consult a group of folks-in-the-know and some of Dallas' power elite for their opinions, which remain confidential. However, I'm always open to other's opinions. If you have a thought of who should be in the top ten and why, email me at vic@victormedina.com and let me know. Don't post it here - email me personally!
