Mexico (though a republican form of government) also has a three party system. Our neighbors to the south could get the same results if the PRD and the “center-left” PRI agreed to caucus together in Congress and support a “fusion ticket” for El Presidente and if they have a Vice El President (Labastida/Obrador?). Their combined vote totals outnumber PAN. Both the PRD and PRI are members of Socialist International and are ultra corrupt, they should get along spendidly. I think the PRI even used to be named PRD.
They could do that, but I don’t see it happening. I think the PRI wants to go it all by themselves, ditto the PRD. Frankly, I’m not very happy with PAN since both their Presidents have produced the “let’s let all the workers move to the USA” mantra that has been an epic disaster for us, and made entire sections of my city, indeed, my own neighborhood, almost unliveable and violent. I couldn’t believe I found myself in agreement with their former Communist PRD Presidential candidate who railed against having these millions of people flee the country.
Frankly, what I’ve seen of PAN, theirs would be the equivalent of a “wealthy/upper class” political party getting control of, say, Michigan, and encouraging all poor folks (read: Blacks) to move to Ohio. Sure, Detroit would improve as a result, but poor Ohio would then have all the problems (like post-Katrina when the NOLA thugs invaded Houston and turned it into a third world paradise).
