Amazing how tightly this is drawn on state lines.

Map Based Upon 120,464 Respondants
I'm not up on my statistics, but is that enough respondents to make a map that detailed?

Depends on how many categories he's putting them into... figure there are 48 states on that map, probably an average of 30 counties in each state... with three 'options'... so that works out to about 4500 'categories', so if it was statistically even thats about 26 people per category... So, for the gross percentages he's working with (30%,50%, etc) that seems ok. Not perfect, but good enough for an undergrad project on geospatial analysis.
But, then again I may just be talking out of my ass. Zak knows this stuff better than any of us.

...as a student of geography, I can say that not only is that an only marginally strong enough number of participants, but the map is misleading because of the way it's filled in. We spent a deal of time studying this except event. It's the same reason why most of the country looks republican when colored by county.
Doing it by county makes certain place appear to have more weight than they do (i.e. Idaho).
The population centers (LA, NYC, DC, Miami, Kansas, Boston) all tend toward soda.

I'm surprised at the extent of the use of "Coke". I didn't think it was that widely used throughout the south.
