Pop: 160 (Blue)
Coke: 152 (Red)
Soda: 226 (Green)
The light colors (30%) mean that I couldn't really tell which one would win a majority, but I went where I think the most population lies.
Missouri - I think the bulk of population would be on the Mississippi River so it goes to soda
Nevada - I think Las Vegas county went for soda, so I made the state go for it.
Oklahoma - Not sure where the population is, but it looks like coke...
New Mexico - I feel more strongly that its coke than Oklahoma
Kentucky - Split between coke and pop. If you think pop won this one then flip it, I have no idea.
North Carolina - Not a damn clue.
Virginia - Think its more soda than anything else.
South Carolina - Leans coke
Wisconsin - If you think the bulk of population is in eastern Wisconsin then flip it to soda.
