## Processing Steps
Oklahoma reports absentee and early votes at the precinct level for every county except for Oklahoma County and Tulsa County, where non-election day votes are reported for the whole county. For those two counties, absentee and early votes were disaggregated to the precinct level by population. Demographic data were aggregated from the block level and precincts were assigned to congressional and state legislative districts using MGGG’s proration software. Precincts for Pushmataha County were digitized to conform to a map provided by the county.
