Everyone should get to make an oath exactly the way they want to...with or without mentioning God...Barack Obama included. And it's no one else's business what decision they make about that or whether or not they want to mention God.

No one else has a frikkin' clue what another person really means when they utter the word "God" anyway...they just have their customary facile assumptions about what they think God is or isn't or what they think someone else thinks God is or isn't...and their assumptions may be quite wrong in that regard...and that's one of the reasons they have no business trying to control whether someone else chooses to say or not say the word "God" when making an oath.

Control freaks of the world, control yourselves instead, as Jeri suggested.
