What's the difference?

Jindal is being skewered so much worse than Tim Kaine was, and I'd put the two SoTU responses about on par with each other.

Maybe it's because the Republicans this year needed it so much more?

Maybe it's because Republicans are criticizing where Dems didn't?

Maybe it's because Kaine was seen to have weak message and delivery while Jindal is seen to have pushed bad message?

I don't know.
