19th C left have been curiously absent, tbh - even the anarchos who you'd expect to be all over this. There might be a lot of them involved, but I've not seen a flag, a left mag or newspaper, nothing ... Izquierda Unida have been saying that they're on our side, but keeping a respectable distance. Mainstream politicos telling us we've got a point, perhaps they'll listen.
I certainly don't think the PP are revelling in it either. Yeah, the PP hardcore are just going to call them perroflautas (dog-on-a-string is "dogs and recorders"), link them to ETA and all the rest. But the PP lost the last election, and they can't win with just the core vote. They don't need loads of young unemployed people on the street talking about them both being the same, to vote for anyone else at all, asking for popular policies they're totally against. Especially when their campaign basically consists of shouting "5m unemployed" at everybody. The government's so unpopular, that they were going to win regardless, this actually puts at least the margin of victory in doubt, if all the swing voters or the people who are sick of Zapatero do something else.
One of the noticeable things about this campaign is that (a) lots of people who don't normally do anything are talking about it and doing something and (b) that everyone is talking about it. That's gonna affect both main parties IMO
(also the PP are clearly bricking it, they keep slagging it off and telling lies about it)
