This has been the question. Some of the blame has been placed on the media (see the Media Influence to learn more) and then it also comes down to who showed up at the polls. Game-changers include:
- Rural voters supported Trump. In general, Republican voters in rural areas has been steadily increasing since 2008, up to 62% Republican in this election. From NPR.
- A majority (roughly 53%) of white women voted for Trump. From NBC News.
- Hillary was unable to keep core states that Obama had won 2008 (such as Wisconsin, Michigan, Pennsylvania, Florida). From American Presidency Project.
