Looking at the maps from Eldiario and uh, something insane I've noticed is that the pro-right trend is much, much stronger in rural areas than in the cities. Most of the provincial capitals are seeing very small right wing swings, but the rural areas are easily seeing swings of +15% for the right.
In fact overall, other than in Huelva province, the rural areas seem to be basically just as conservative as the cities (maaybe they are still a couple points left wing, but not by much, if at all)
I suppose something to ponder if you believe in #globaltrends
As ever, I don't think we need to look to #globaltrends to explain anything. The Andalusian PSOE always governed in a basically clientelistic way and as far as I can tell, the Andalusian PP hasn't tried to dismantle any of that (not touching the PER, for instance, as you might generically expect a right-wing new broom to want to do) but instead just coasted on being the new incumbents while also not having decades of baggage. It makes sense that there'd be a pro-incumbent shift in former PSOE bastions under those circumstances.
