I think Kane from C&C would make a good president because he  inspires respect, fear and loyalty with nothing else but the sound of his voice (you thought Obama was good at speechs). Also how many presidents can say they survived a ion cannon? Yeah theres some credentials.
Ryu would make a fine VP due to his pro martial arts stance on everything plus he spearheaded the research into Haduken based energy which is 100% green; beat that climate change!
