Presidential rankings tend to reward those on the left and penalize those on the right, which is where PragerU comes in. The conservative education-and-media outlet said it sought to provide a "fuller, more balanced picture" with its first Presidential Rankings Survey, using a flexible methodology and including scholars, historians, media figures and politicians typically overlooked for such ratings despite their expertise. "For decades, most presidential rankings have come from a narrow, left-leaning perspective," said PragerU in its Sunday release. "Our Presidential Rankings Survey sets out to broaden the conversation by inviting voices and viewpoints that are often ignored."
