Research, microtargeting & polling projects
- Over-sample Hispanics
- Use Spanish language interviewing. (Monolingual Spanish-speaking voters are among the lowest turnout Democratic targets)
- Over-sample the Native American population
The lower the expected turnout of a particular demographic, the higher the margin of error if you survey that demographic in proportion. Remember the story recently of the single black student who skewed a poll by 3% every time he responded?
