2026 is a midterm (year 2) year in the 4 year presidential cycle. The same monthly seasonality recomputed using only prior midterm (year 2) years (2014, 2018, 2022) often tells a very different story. Months where the cycle phase diverges most from the long-run average are where seasonal edges either compound or evaporate.
