10/27/2022

## Sources
The RDH retrieved the VEST 2020 primary precinct boundary and election results shapefile from [VEST's Harvard Dataverse](https://dataverse.harvard.edu/file.xhtml?fileId=5706487&version=33.0)
The RDH retrieved raw 2020 primary election results from the Open Elections(https://github.com/openelections/openelections-data-ms) and precinct shapefiles from VEST's Mississippi 2020 file.

## Notes on Field Names (adapted from VEST):
Columns reporting votes generally follow the pattern: 
The first character is G for a general election, P for a primary, S for a special, and R for a runoff.
Characters 2 and 3 are the year of the election.
Characters 4-6 represent the office type (see list below).
Character 7 represents the party of the candidate.
Characters 8-10 are the first three letters of the candidate's last name.
One example is:
G16PREDCLI

To fit within the GIS 10 character limit for field names, the naming convention is slightly different for the State Legislature and 
US House of Representatives. All fields are listed below with definitions.
Office Codes Used:
PRE - President of the United States
USS - U.S. Senate
CON## - U.S. House, accompanied by a CON_DIST column indicating district number

## Processing Steps
    
The RDH joined additional election results to VEST's existing precinct shapefile, including President, U.S. Senate, U.S. House using Python.
For more information on the processing completed, visit our [Github repository](https://github.com/nonpartisan-redistricting-datahub/erj-ms) for Election Result Joins (ERJ) for Mississippi.
Where possible, the RDH validated the election results we processed against Mississippi's Secretary of State's election results. For additional races the RDH manually checked state totals. For more information on this comparison, please see our processing on Github (https://github.com/nonpartisan-redistricting-datahub/erj-ms).

## Additional Notes

Election Results matched State Wide totals except for in Issaquena county. Election Results were not available for the Democratic primary in Issaquena county. The MS-SOS has been contacted.

In the congressional files, the CONG_DIST column only has values for districts where an election occurred at that level in the file.
