Just my $0.02 (with my rudimentary knowledge of Spanish politics):

The PSOE (who eventually came around to our side) can't form Government outright, even with the support of Sumar (the more radical left-wing party).

Which leaves us with the PP (mainstream conservatives + some right-wing nutters). Again, no outright majority, but they look more likely to me to form some kind of coalition.

Besides that, there are the two Catalan parties. Too small to matter, and I really doubt they have any interest in a lithium mine on the other side of the country.

Unless you factor in some kind of black swan (eg Russian interference, which maintain could be at least a minor problem), I doubt it would be an issue for us.

But I'd love to hear more from MOR1 and boxbcn.
