Why no “time to election” curve? Unlike pollsters — where we have every poll with its field dates — our forecaster archive (JHK Forecasts) stores only each outfit's final pre-election forecast per race, not its earlier snapshots. So a lead-time breakdown genuinely isn't in the data for forecasters. Pollster pages do show it (e.g. the leaderboard).
