Obama decides that Gensokyo is bloody amazing and decides to challenge Kanako, Byakuren, Miko, etc, to gain religious control so he can become the top dog. And then he engages in a drinking duel with Suika because he never got to drink much as president.

(That was in a joking/whatever tone, maybe. I still want to see Obama launch a spell card, even if it's not due to anger.)
