This is from someone else's scenario on soc.history.what-if ( [link]
): basically, the US Socialist movement does rather better, Eugene Debs wins the Presidency on a Socialist ticket, the panicked right tries to prevent him from taking office, and there is a genuine revolution as a result...
For the curious, Poland broke away during the Soviet near-collapse in the late 90s, has turned its back on Communism more thoroughly than any other ex-Soviet puppet and has a hardline nationalist and Very Catholic government, although not actually a theocracy. Spain as OTL had a civil war in the 30s, and with Germany, Italy, France and the UK (gone a bit red scare bugshit after the US went Red (or at least a dark shade of pink)) supporting the Franco-equivalent, Spain went *fascist: they later sent troops into Portugal when revolution threatened their right-wing allies in Portugal, and apparently forgot to leave.
The Catholic Pact is a new political creation, with Poland allying with the most ideologically compatible nation in Europe, and Parguay, one of only two remaining rightist juntas in Latin America (propped up by xenophobia re their neighbors) jumping on the bandwagon in hopes of getting a bit of aid. The Columbians aren't taking the risk of offending anyone by joining, and anyway the Spanish and the Poles consider them waay too feckless.
Iberia is a bit of a right-wing "north Korea", poor, isolated, and armed with WMDs: it's a bit better off in that it at least has local capitalism and there isn't actual starvation (farming can be done at a profit), although the continued growth of the population (birth control is illegal, as is abortion) may change this in time.
