Demographics
Research on the Never Trump movement shows that Mormon and female Republicans were the most likely groups to oppose Trump's candidacy while non-Mormon and male Republicans were the most supportive. In the same study, establishment Republicans were found to be more likely to support Trump's candidacy, the opposite of what most observers, including Donald Trump himself, claimed.
