It's never too late to plan for 2022.
Download this free 2022 vote goal worksheet to help calculate the number of votes you need to win per precinct, based on 2018 performance.
If you didn't run for office, pick a candidate in a similar race and whose performance you except to match, e.g., if you're running for County Commission, pick a candidate similar to yourself that ran for that same office.
You'll need to update voter registration numbers up until 2022's close-of-book voter registration totals to get up-to-date numbers.
The spreadsheet automatically then automatically calculates the numbers you put in and gives you a running total per precinct on the far right.
