Each axis runs from −10 to +10, with zero a genuine mixed or balanced position rather than an absence of opinion. A score describes a stated position and a governing record; it is not a judgement of merit. What each score means →
Core principles
A party built to institutionalise a revolution and end military coups, which then held the presidency for seventy-one consecutive years.
Economic model
Land redistribution and oil nationalisation, then import substitution, then NAFTA and privatisation under the same banner.
Organisation of powers
Elections held every six years and never lost until 2000; presidents chose their successors by private designation.
Reading note
Vargas Llosa called it the perfect dictatorship because it rotated its leader every six years and never needed to suspend the constitution.

How it moved
Positions are recorded at dated anchor points tied to a documented moment — a programme adopted, a government formed, a reversal. Nothing is interpolated between them, because nothing is known between them. Figures in amber moved by two points or more from the previous anchor.
| Anchor | EC | CU | AU | SC | ID | CH | What it is tied to |
|---|---|---|---|---|---|---|---|
| 1929 | −02 | +03 | +07 | +06 | +03 | −03 | Founded after the assassination of a president-elect, to route succession through a party rather than through the army. |
