Voteview

Voteview is a brand that allows users to explore and analyze congressional votes throughout American history. With their interactive platform, users can view congressional roll call votes on a map of the United States and a liberal-conservative ideological map. This brand provides valuable information about the ideological positions of voting senators and representatives, classifying them as either liberal or conservative.

The original Voteview was developed by Keith T. Poole and Howard Rosenthal in the late 1980s and has since evolved to incorporate new features and data. Voteview utilizes the DW-NOMINATE procedure to calculate ideological positions, which allows users to understand the spatial proximity of legislators' voting records.

This helps users better comprehend the dimensions that shape congressional voting behavior, particularly the distinction between liberal and conservative ideologies. Sponsored by organizations such as The William and Flora Hewlett Foundation and the National Science Foundation, Voteview is a trusted resource for understanding the political history of the United States
