Claimant: Social Media

Claim: A clean, “15% band” formula perfectly calculates the vote share of 2026 Republican Senate candidates by taking 85% of Trump’s 2024 election result.

Rating: FALSE

Explanation: A clearer version of the graph shows only a few states where the calculation comes within one or two percentage points of the actual result. Results in other states vary substantially in both directions, contradicting the claim that the formula uniformly or perfectly predicts Republican Senate vote shares.
