It appears this image of mine (made after Zappy's Al Quaeda-backed coup) was strangely prescient:
I haven't any idea. The Socialists have made a beeeg mistake for the sake of socialism. I try to keep in mind they and Aznar's government was with us, and they did have some level of support. I hope those people fight.. but if they will not.. so be it. If they try to 'nuance' them, when the Islamists step up their demands, you know what's going to happen already. They will use terror to get their way... no matter what.
He may look like Zapatero, but he's not diabolical.
NOTHING about this is funny.
Like Britain, Spain is a constitutional monarchy, so they don't have a President. Zapatero is Prime Minister. If parliament gave him a vote of no confidence today, there'd be another election soon.
Zapatero only won by five percent in the popular vote and 16 seats in the legislature. There are plenty of minor parties, so it's possible that if one or more of them turned against him, or if a major chunk of Zapatero's own party became disaffected with his course of action, his government could fall.
But usually it takes more than ideological disagreement to topple a ruling coalition -- all the more so, since some of the parties in parliament are actually to the left of the Socialists, and support their policies, and since party discipline is greater in Europe than here.
