Why no crazy Ted jokes?

So .. when President Ronald Regan announced that he was stricken with Alzheimers the slamming and bashing was on.  Suddenly, everyone pounced on the man claiming his disease was the reason he did the things he did.

Where are the jokes about Ted Kennedy?  Why no jokes about his liberalism and his brain cancer?  No slams about his singing off-key in Spanish because of the pressure on his brain?

I know it isn’t nice.  But it wasn’t nice when it was President Regan either.
