First, he is not a hero. Second, doing an action movie where there is no bodily risk is not heroism. Real heros generally are not paid millions of dollars to playact. They sacrifice, many time their all.
“My question. What qualification does a ‘movie action hero’ have that would make him qualified to be ‘president’.”
Schwarzenegger might be qualified, not in a Constitutional sense but in a practical sense, because he is governor of California. The story mentions this at the outset.
Anyway, being an action hero would not qualify one to be president, whether you were heroic on the screen or in real life. Some people will disagree with me on this, citing Washington, Jackson, Grant, Eisenhower, etc. But of course those men weren’t elected because they threw themselves into the breach. They were elected, mostly, because they proved themselves able administrators.
