America's vice president delivered many robust bursts of laughter last night, laughter that seemed (to us) to mean the usual "Oh come on, Paul Ryan, you are a ridiculous liar."
But there are varying opinions! Those on the right, for example, would never vote for Obama-Biden–and they are none too pleased with this Joe Biden and his laughter. Why, they have even less intention of voting for him now, if that's possible.
The important question is whether anyone is trying to "spin" this on Twitter.
