Is the New York Times bestseller list politically biased?

I think it’s biased towards people that enjoy reading books, which rules out roughly 95% of conservatives.

It's first and foremost financially biased. They are absolutely complicit in allowing publishers to play games to make it look like a book sold a ton in a week to get the stamp on the cover. It wouldn't surprise me if they were less willing to allow books they don't like to play these games.
