Replication data for: A Bridge to Somewhere: Mapping State and Congressional Ideology on a Cross-Institutional Common Space

First, there has been a scarcity of longitudinal roll call data. Second, even where such data exist, scaling ideal points within a single state is inadequate.

No comparisons can be made to other state legislatures or Congress. Our project suggests a solution to both of these problems. We use a new comparative data set of state legislative roll calls beginning in the mid-1990s to generate ideal points for legislators.
