We have a clip from this week's new episode of Smallville, "Requiem." In this scene, Clark and Lana go to visit Oliver in the hospital after he's injured by an explosion at LutherCorp to try and figure out who did it.
Clark: My father says you learn more about yourself when you lose. Lex: What'd you learn? Clark: That I'm not destined to be a politician. You need two different personalities. Lex: You don't need to be an elected official to change the world, Clark. Clark: Have you ever thought about getting into politics? Lex: Someday I'd like to be president.
