Nope.So the President is supposed to stop everything and mourn? Where is the precedent for that?
But he should quite probably avoid flippant and pleasure-seeking activity, a metaphorical 10 seconds after making such a somber announcement.
Right-Wingers care much more about style than substance. Ronald Reagan & George W. Bush are proof.
You say this when just yesterday Obama talks about how the "optics" didn't look good???????????
Oh let's be serious, elections are entirely about "optics" for any and all candidates of any and all parties.
We're not electing candidates --- we're buying products. It's set up that way intentionally. It's no accident that we describe party ideologies using the word "brand". Style always takes priority over substance.
