Key Insight: The 2018 U.S. House elections saw a notable shift: voters previously less concerned with race and gender issues swung strongly toward Democratic candidates.
Why? This change occurred despite Republican appeals to counter-racism and anti-sexism, suggesting Trump's divisive rhetoric inadvertently normalized these factors as politically relevant.
What Changed: Hostile sexism and denial of racism became stronger predictors for House votes than in 2016.
This increase stemmed from a crucial realignment: voters with less racist/sexist attitudes shifted away from Republican candidates.
How Researchers Explain It: This phenomenon signals that Trump's explicit hostility toward minorities and women may have transformed these issues into central components of the GOP brand, ultimately creating an electoral penalty for Republican nominees in 2018.
