electiondata - Version 2.0 Release

Changes since Version 1.0:

Requirements: - python3.9 - Some later package versions -- see requirements.txt

Running the software: - Main parameter file no longer required to be run_time.ini in current directory (though that is still the default) - Database name no longer required to be given in the main parameter file (though that is still the default) - Headers for parameter files have changed: [electiondata] instead of [electiondataanalysis] in the main parameter file; result parameter files need header [election_results] - Module and repository name changed to electiondata; submodule names changed to remove underscores.

Database

• Structure has changed substantially, and new code is not backwards-compatible.
• BallotMeasureSelection table no longer exists; instead, ballot measure selections ('Yes' or 'No') are treated as CandidateSelections with Party 'ballot measure selection'.
• Census and other external data now stored in two tables: ExternalDataSet to hold metadata, and ExternalData to hold data.

Jurisdiction Prep

• There are no longer Election.txt files in the individual jurisdiction folders, but a single Election.txt file in the jurisdictions/000_for_all_jurisdictions folder.

Data Loading

• By default, the following data loading routines will decline to load the files for a particular jurisdiction and election to the desired database unless they pass the tests in Analyzer.testloadedresults(), including comparison to reference result contest totals:

  • DataLoader.loadejpair()
  • DataLoader.load_all()
  • loadorreloadall() Each of these routines has an optional parameter `runtestsdefaulting to True. IfFalse`, data will not be tested .

• File structure for mungers has changed substantially. Each munger is defined by one *.munger file, and all those files are in the mungers directory.

• Munger parameter scheme has changed substantially. See User_Guide.md.

• Handling of munge formulas has changed, allowing more flexibility in combining parameters, but requiring that certain reserved characters be avoided. See User_Guide.md.

• For flat text files, strings that are in the headers of the count columns are now referred to by, e.g., rather than .

• If the rows_to_skip parameter is 1 or more, these rows are removed as the file is read, and all other row numbers should not count the skipped rows. For example, if rowstoskip=2, then countheader0 references the third row of the original file.

• json and xml files can be munged.

• Multi-block text flat text files can be munged.

• Values to ignore (e.g., Candidate=Total) can be specified.

• Handling of lookups in auxiliary files has changed substantially. See User_Guide.md.

• Ballot Measure contest functionality has not been tested and is not guaranteed to work correctly.

Error reporting

• Errors are now recorded in files in the directory given by the reports_and_plots_dir parameter specified in the main parameter file
• All data loading routines have suppress_warnings parameter allowing user to keep error reporting but omit warnings (such as CandidateContests not found).

Exporting and Analyzing Data

• There are substantial changes to the routines and parameters for exporting and analyzing data. See User_Guide.md.

Testing

• tests/load_and_test_all.py is no longer available. Instead, run pytest tests/dataloading_tests.
• Added reference results for testing correctness of uploaded data. Note that reference results use the convention that, e.g., 2021 Democratic Primary and 2021 Republican Primary are two separate elections. Some of the mungers for pre-2021 Primary Elections have not caught up with this change.
• tests directory also contains tests for Analyzer and JurisdictionPrepper functionality (applied before each pull request touching code)

electiondata - Version 1.0 release

This codebase allows ingestion of state-level election datafiles into a common data format stored in a postgres database. Processing files for number of states are already included but additional states will be constantly added. Additionally, this codebase provides a number of analysis methods, such as aggregation and visualization.
