The USA had dropped below the “democracy threshold” (+6) on the POLITY scale in 2020 and was temporarily considered an anocracy (+5). It had also lost its designation as the world’s oldest, continuous democracy; that designation now belongs to Switzerland (171 years), followed by New Zealand (142) and the United Kingdom (139). Further degradation of democratic authority in the USA will trigger an Adverse Regime Change event.
The downgrade can be tied directly to the Trump administration’s actions over the past four years:
In 2019, CSP changed the USA code for Executive Constraints from 7 to 6 due to the executive’s systematic rejection of congressional oversight; dropping its POLITY score to +7 and resetting its DURABLE score to “0”. In 2020, the coding for Executive Constraints fell another point or two due to the executive’s systematic purge of “disloyalists” from the administration, forceful response to protest, vilification of the main opposition parties; and undermining public trust in the electoral process, reducing the USA POLITY score in 2020 to +5 (anocracy).
While the score has since risen from +5 to +8 under President Joe Biden, it's deemed alarming that the US' Polity score fell so far.
