order to join them to the precinct shapefile. Ceratin precincts in the shapefile and in the results were merged in order to reconcile discrepencies. Demographic data was aggregated from the block level using MGGG’s proration software. Congressional and state legislative district IDs were assigned to precincts also using this package. MD_precincts includes only votes cast on election days -- it does not include early, absentee or provisional votes, because those are only reported at the county (not precinct) level. MD_precincts_abs does include early, absentee, and provisional votes, which were disaggregated to precincts using MAUP, and added to the day-of results. ## Additional Notes Rating from MGGG: We give these shapefiles an A rating. All data was obtained from the state government and was processed by MGGG staff.
