Abstract: An ongoing debate in American politics concerns the extent to which subnational politics has become “nationalized.” We advance this debate by collecting issue‐position data on four distinct policy topics from unprecedented national surveys of public officials at both the local and state levels. We then combine this survey data with precinct‐level presidential vote‐share data that is tabulated to match the boundary of each survey respondent's government jurisdiction. In doing so, we demonstrate that national party sorting of subnational officials is substantively and statistically significant across a range of issues with national salience, that it is consistent across local and state levels of government and it cannot be explained by the party sorting of constituents. These findings have implications both for the scope of nationalization as well as its implications for substantive representation.
