New research suggests that men insecure about their masculinity tend to support the president more. No, really:
We found that support for Trump in the 2016 election was higher in areas that had more searches for topics such as “erectile dysfunction.” Moreover, this relationship persisted after accounting for demographic attributes in media markets, such as education levels and racial composition, as well as searches for topics unrelated to fragile masculinity, such as “breast augmentation” and “menopause.”
In contrast, fragile masculinity was not associated with support for Mitt Romney in 2012 or support for John McCain in 2008 — suggesting that the correlation of fragile masculinity and voting in presidential elections was distinctively stronger in 2016.
The same finding emerged in 2018. We estimated levels of fragile masculinity in every U.S. congressional district based on levels in the media markets with which districts overlap.
[I]t remains to be seen whether any link between fragile masculinity and voting will persist after Trump exits the national stage. We suspect, however, that Trump’s re-engineering of the GOP as a party inextricably tied to many Americans’ identity concerns — whether based on race, religion or gender — will ensure that fragile masculinity remains a force in politics.
Again, it's not the size of the correlation that matters, it's how we use the data.
