Because the books are relatively new releases (they’ve all come out since late June), they’ve received quite a bit of recent promotion, which might be why people are particularly interested in them this week. D’Souza’s Hillary’s America has a companion documentary in theaters now.

Ultimately it’s the length of time a book stays on the bestsellers’ list, and not one single week’s appearance, that shows it really resonates with readers. If Hillary’s America and Armageddon manage to stay on the bestsellers list, which currently includes Ta-Nehisi Coates’s Between the World and Me (48 weeks on the list) and Malcolm Gladwell’s Outliers (55 weeks), Clinton might well have something to worry about.

The rankings published by the New York Times are for print and ebook sales combined from the week ending July 23, 2016. The Times doesn’t disclose how it creates its rankings, but says it’s based on reports from booksellers across the US and that “sales are statistically weighted to represent and accurately reflect all outlets proportionally nationwide.”

All three books also appear in the top 25 bestselling books on Amazon, which includes fiction and nonfiction.
