If I may, I'd like to confuse Stu's response on the way toward a cleaner
answer (well, try for cleaner, anyway).
for Chi sq, look in the equation and you will see the numerator is the
square of the difference of observed and expected. So any deviation from
expected will increase the total chi-sq

Perhaps it's just a matter of getting a meaningful denominator. Certainly the
100% of each group which the Gallop presentation uses seems to do violence to the
concept of proportional. As Elliot Cramer writes it also doesn't make much sense
to use the percent approval before 9/11. But isn't it
one traditional way of comparing changes in percentages to to transform to
z-scores and then subtracting. I think this is what signal-detection people
call D-prime.
