Fair gives Republicans 51.6% of the 2028 popular vote
That is a 68% chance of winning it. In the backtest, this model’s typical miss was ±3.4 points, so 80% of outcomes would land between 47.0% and 56.3%.

How it works
Ray Fair has published this equation since 1978. Voters reward the party in power for growth in the election year and punish it for inflation over the term.
It also counts the quarters of strong growth (over 3.2% a year per person), whether a sitting president is on the ballot, and how many terms the party has held the White House.
Here it is re-fitted on 1948–2024 with the data as it was published before each election. Fair’s war-year term is dropped because only 1948 uses it.
If the election were today: Fair's G uses growth over the latest three published quarters (to 2026 Q2), P uses inflation over the 6 published quarters of the term, and Z (2 strong quarters of 6) is scaled to 15 quarters.
The fitted equation
| Term | Coefficient |
|---|---|
| Constant | 50.590 |
| Democratic incumbent party | −1.239 |
| Growth per person, election year | 0.958 |
| Inflation over the term | −0.852 |
| Strong-growth quarters | 0.547 |
| President running | 3.720 |
| Terms the party has held power | −3.264 |
Its record
Predicting each election with a version fitted without it, the model’s typical error is ±3.4 points and it called the popular-vote winner in 14 of 20 elections. It missed 1948, 1960, 1968, 1988, 2016, 2020. See every election.
