Zapatero is to blame.
Sometimes memory plays tricks on us, we rarely remember why in the past we preferred one option over another, in the case of our political leaders it seems evident what the motivation is.
Zapatero with his Venus in trine with the sun, with a practically exact aspect, indicates to us that this is a person suited to managing a time of prosperity, also with his sun in Leo in conjunction with the ascendant points to an individual with capacity to play a leadership role in any field. However the lack of dissonant aspects in a natal chart usually also indicates difficulties in facing a crisis of magnitude, it seems rather the natal chart of an individual born to manage a fortunate moment, a moment of social or economic fluidity.
It seems a logical sign that at a popular level there is a tendency to choose based on the general socioeconomic situation, Zapatero was elected at a time when there were no major difficulties and the economy was flowing, and for that he has been a good president trying to improve social conditions, when the situation turned around he simply stopped being useful, but do not doubt that once a favorable situation returns there will be a tendency to elect a person with similar characteristics.
However in the case of times of difficulty there is a preference for those more inclined toward control or the capacity to limit.
I do not see a culprit in the current situation, we are all culpable, we all choose what interests us most, and what interests us depends on the circumstances.
If the political class had a real interest in benefiting society, they would function like a football club, signing the best players without worrying too much about their past or belonging to a rival group,
Finally the public ends up accepting it since we all want our team to be the winner regardless of where the player comes from. Why doesn't this happen in politics? Aren't they supposed to look out for the general interest? It is absurd to think that they prioritize particular interests, but that is what seems to be happening.
