Select two candidates to compare. These candidates do not need to be running in the same contest. The ratio displayed will show the votes for the top candidate over the votes for the second candidate. Some abnormal patterns, especially when viewing the rolling block ratio, show more clearly when a different order of candidates is selected, You may also specify a specific precinct, tabulator, or the method that the vote was cast. If no choices exist, that means that the Cast Vote Record did not include that information. The "block size" will show the graphs broken down by that number of consecutive ballots. Our analysis has shown that viewing the data in 100 or 1,000 ballot blocks is optimal for spotting unusual voting patterns, and often these patterns show more clearly at different block sizes, so it is recommended to try numerous block sizes.
