I think perhaps we are giving more credit to the ooposition for changing the subject and sticking only with what they are allowed to talk about.

I am beginning to think they just don't get any points being made.

They are at a distinct disadvantage in many respects becuase when they get a subject not covered by talking points they either have to wing it or try their best to fit anything into the limited scope they have.

What other explanation could there possibly be for being off topic consistently.....(sarcasm).
