Pre-Election Preparation
Pre-Election Preparation Election Day Precincts: No Special Prep AV Counting Board: Get Organized Process and store ballots in batches no larger than individual precincts. Smaller batches (25-100) may be necessary for a Comparison Audit.
Election Day Precincts: Follow Existing Procedures Ballot Accounting and Chain of Custody General Security AV Counting Board: Execute
Post-Election Preparation Secure and clearly ID Provisional Envelope Ballots that are counted Determine Risk Limit Compile Results from Target Race(s) Create the Ballot Manifest [Get Cast Vote Record Data from County Clerk – Comparison Audit Only] Obtain Seed Selection Hardware
Post-Election Preparation Secure and clearly ID Provisional Envelope Ballots that are counted Determine Risk Limit Compile Results from Target Race(s) Create the Ballot Manifest [Get Cast Vote Record Data from County Clerk – Comparison Audit Only] Obtain Seed Selection Hardware
Seed Selection->Ballot Retrieval->Tallying The Audit Event Seed Selection->Ballot Retrieval->Tallying
The Audit Event Seed Selection->Ballot Retrieval->Tallying Purpose: to create a randomly generated “seed number” so the RLA tool can randomly generate the list of ballots to be examined.
The Audit Event Seed Selection->Ballot Retrieval->Tallying Process: use a physical source of randomness such as rolling dice or drawing cards to create a 20 digit number. Example: randomly select 20 people from the audience to roll dice; the resulting 20-digit number becomes the seed number. Demo using dice and sign in slip with doc cam.
The Audit Event Seed Selection->Ballot Retrieval->Tallying Purpose: to retrieve the ballots to be examined.
The Audit Event Seed Selection->Ballot Retrieval->Tallying Process 1 – Countdown Method: using the list of randomly selected ballots created by the RLA tool, locate the ballot container, remove the ballots from the ballot container, place them in a stack on a table, and count down to the ballot(s) specified for that precinct. Demo using stack of paper and ballot pull list with doc cam.
The Audit Event Seed Selection->Ballot Retrieval->Tallying Process 2 – K-Cut Method: “Cut” the stack of ballots like a deck of cards for a predetermined number of times (5-6). The ballot that ends up on top is the ballot selected. Demo using phone and stack of paper with doc cam.
The Audit Event Seed Selection->Ballot Retrieval->Tallying Purpose: to document the results for the targeted race(s), and any other races being examined on the selected ballots, so those results can be entered into the RLA tool.
The Audit Event Seed Selection->Ballot Retrieval->Tallying Process: audit teams examine the ballots and hand-tally the votes according to the Michigan standards for interpreting ballot marks. The results are entered into the RLA tool, which compares the results of the sample to the reported election results and determines the risk-limit.
Event Planning and Costs Space for ballot retrieval and tallying Technology – computer(s), printer/copier, document camera, video displays Staffing – how many and for how long? Supplies – slip sheets, labels, tally sheets
2018 Kalamazoo Pilot RLA Spending Supplies <$50 Staffing $125 Food $450 Total $625
2019 Projected RLA Spending Supplies <$50 Staffing $384 Food ~$75 Total $509
Future Considerations for Cost/Staffing Involvement/role of state RLA tool capabilities Impact of coordination by county Ability to estimate # of ballots to examine
