Historical mode shows canonical county presidential rows. Advisory indicators are not evaluated for this state-year because same-grain comparison rows are not loaded. Vote methods, equipment, and administration records remain 2024 context and are not overlaid.

58 visible reporting jurisdictionsAbout the directional review column
The column below is not a finding that interference occurred, and it does not prove that any candidate actually received extra votes. It is a rough advisory screen from the loaded review indicators. For down-ballot comparison flags, the app compares same-party presidential votes against a comparison race such as U.S. Senate or Governor, then labels the direction with the larger relative gap. Governor-only comparisons are marked low confidence because they can mostly reflect ordinary race-specific ticket splitting. When the comparison is U.S. House, the column names presidential-over-House dropoff direction instead of candidate benefit because House races are district- and candidate-specific controls.
That direction can be affected by split-ticket voting, incumbency, local candidate strength, undervotes, uncontested races, one-sided comparison races, reporting-unit definitions, missing comparison rows, or ordinary political geography. Treat it as "if this pattern needs review, this is the side the math points toward," not as a causal claim or a conclusion.
