The Presidents of the United States

First, FOX introduced us to the first African-American president of the United States on "24."
Then, ABC welcomed the first female president on "Commander-in-Chief."
Now, NBC has the first Latino president on "The West Wing."
It's too bad 24 killed off President Palmer this season, Commander-in Chief is in risk of cancellation and President-elect Santos has only a couple of episodes left before the West Wing ends its run on NBC. Whoever said it would last, right?
