I have been presenting various versions of a model to predict the outcome of upcoming Democratic primaries. The earlier version of the model worked like this: Make some assumptions about the ratio of voting preference (for Sanders vs. Clinton) among the different major ethnic groups, and using the known distribution of said ethnic groups, predict the future.
I started out with the assumption that among whites, the ratio would be 50:50, based on one datum, the outcome from Iowa, which is essentially a white state. I used a bias for African Americans and Hispanic voters favoring Clinton.…

As you know, I developed a simple model for projecting future primary outcomes in the Democratic party. This model is based on the ethnic mix in each state, among Democratic Party voters. The model attributes a likely voting choice to theoretical primary goers or causers based on previous behavior by ethnicity. Originally I made two models, one using numbers that the Clinton campaign was banking on, and one using numbers that the Sanders campaign was banking on.
