Institutional Revolutionary Party and US Republican Party
Measured distance across six axes
The same broad family. They agree within three points on CU, ID, CH. No axis separates them by eight points or more.
Axis by axis

|---|---|---|---|---|---|
| EC · Economic organisation | +01 | +06 | 5 | Differs | Real difference, but not the dividing line. |
| CU · Social and cultural order | +04 | +06 | 2 | Agrees | Effectively the same position. Not what an argument between them is about. |
| AU · Organisation of power | +08 | +03 | 5 | Differs | Real difference, but not the dividing line. |
| SC · Scale of decision | +07 | 00 | 7 | Differs | Real difference, but not the dividing line. |
| ID · Rule of membership | +03 | +04 | 1 | Agrees | Effectively the same position. Not what an argument between them is about. |
| CH · Method and tempo | −04 | −03 | 1 | Agrees | Effectively the same position. Not what an argument between them is about. |
Each axis runs from −10 to +10; the distance is the straight-line separation across all six at once, out of a maximum of 49.0. How the scoring works →
The evidence behind the widest gaps
A distance figure is worth nothing unless the scores behind it can be checked. These are the artefacts supporting the axes that separate these two most.
PRI · SC +07
Coded +7: governors and state parties subordinated to the presidency through the dedazo.
- Documented act or statutePresidents designated their own successors and the party's state candidates by private nomination.
GOP · SC 00
Coded at zero: federalist in doctrine and centralising in practice on the issues it prioritises.
- Programme textStates' rights invoked on education and health, while federal preemption is sought on immigration enforcement and energy permitting.
What this comparison does not establish
Proximity means similarity of stated position. It carries no claim about competence, circumstance, scale of operation, or what either organisation actually did to the people under it. Two organisations can sit close together and produce entirely different histories, because those things are not on any axis and could not be.
Institutional Revolutionary Party
1929– · Mexico
A party built to institutionalise a revolution and end military coups, which then held the presidency for seventy-one consecutive years.
US Republican Party
1854– · United States
Limited federal government, lower taxes, strong defence, religious and family traditionalism, gun rights.
Distance is not the whole answer. Two organisations can sit the same distance apart for entirely different reasons, and the reason is the content of any claim about them. Open the comparison in the atlas to weight the axes yourself.
