Google searches for “voter registration” have surged across the US this week, particularly in areas with large Hispanic populations, according to a report from The Upshot, the New York Times’s data journalism website.

On Wednesday and Thursday, the leading markets for the search terms “register to vote” were in disproportionately Latino areas of Texas, California, Nevada, Florida and Arizona – regions which historically have some of the lowest registration rates in the US.

The surge coincides with the controversy over Alicia Machado, the Venezuelan-born former Miss Universe whose story was wielded by Hillary Clinton at Monday’s presidential debate as an example of Donald Trump’s attitude towards women and Hispanic people.

Ms Machado, who recently became a US citizen and has campaigned for Ms Clinton, says Mr Trump called her “Miss Piggy” and “Miss Housekeeping” after she gained weight following her Miss Universe win in 1996. Mr Trump has responded by attacking Ms Machado’s character and doubling down on his criticism of her weight-gain.

Whether or not the voter registration searches can be attributed to an “Alicia Machado effect”, they represent a major change from last month, when, The Upshot reports, “registration searches were highest in the predominantly white, Northern states that typically have the highest registration and turnout.”
