Your quote by Obama re "A light will shine down" is from a speech in which he was poking fun at himself. John McCain famously used it in a campaign ad and was roundly laughed at himself for either not grasping the context, or grasping it and using it anyway, knowing that his Republican voters would be too dim to. And here you are eight years later...

The Pelosi quote is true, however.  But that's just it—it's her quote, not Obama's.
