The main focus of the package is to give weighted party support and issue attitudes by demographic groups over time. As of 0.2.0, policy-issue and vote data are read on demand from the cp3 project's hosted Parquet files (see update_cvpa_data()) rather than bundled with the package, covering several hundred policy questions across seven issue domains in addition to vote choice/intention. The vote data are described in Lucas, Romualdi, Armstrong, and Goodyear-Grant (2025)
