CBS News/YouGov: Close races in AZ & NV, Hillary way ahead in VA

Why is Nevada not moving hard to Clinton like Colorado did? Nevada should be more demographically favorable

Nevada and Colorado are Democratic for different reason. Nevada because it's non-white population is large and growing and Colorado because it's large college educated population (and growing Hispanic population). It's easier to poll college educated whites than Hispanics and Asians, so Colorado shows a more consistent Clinton lead.

In the end the margin was 4 points higher.

Yes, but Democrats also outperformed the polls in most other states that year (especially in NH, IA and CO).

Democrats underperforming the polls in white states and overperforming the polls in minority-heavy states? What a twist.
