Have the Democrats suppenly taken an interest in morals?

Question

I believe the democrats have suddenly developed a keen sense of morality. John Edwards has been banned from making a speech at the democratic convention for having an affair and lying about it.

In his place Bill Clinton spoke.

What am I missing?

Answer 1

Would rather have heard Edwards explain why he admitted it.  

Answer 2

seems so, at least when it is convenient.

Bill, of all people?   lol
