That is a general newslink, which does not show the polls to which you are referring at all.
I would assume you are however referring to
SONDAJ - Monarhia pierde teren după retragerea Regelui Mihai şi excluderea Principelui Nicolae - Stiri pe surse - Cele mai noi stiri - the most recent polls conducted, referenced earlier in this thread. They show a 4,6% drop in support for the monarchy, after the events surrounding Nicholas M-M and the illness of H.M the King. As a comparison, the monarchy in Norway tends to suffer a 10% fluctuation whenever there is strong criticism of a specific event, down for a while, then back up when the storm calms. That is a natural reaction of people who are unsure about recent events, and in this specific case, I would say it is miraculous that the monarchy hasn't taken a heavier blow following the uncertainty of the line of succession. I would just add that the removal of Nicholas M-M from the proposed line of succession should in no way change the views of the Romanians when it comes to the monarchy, because as you have said over and over, Romanians are not in favour of the Royal Family in Romania continuing, but would instead wish for a new Hohenzollern Prince taking over as King, when that time comes, right?
Seems inconsistent to me.
The poll further shows that the Crown Princess is seen as great/good by 40% of the population, while 40% have no firm view on her. Only 14% have a negative view of the Crown Princess and Custodian of the Crown. Could you find any elected official with such numbers? With the exception of a few, I think you would struggle to even find a royal anywhere with that kind of support.
The Royal House of Romania is seen as great/good by 44% of the people, 37,7% have no firm view and 12,9% have a poor or very poor view of the family. I don't think it's even necessary to compare these numbers to those of other monarchies around the world. They are almost above any monarchy currently in existence.
The King is sick, and the one seen as the future heir is currently in a state of limbo in Romania, and the support for the monarchy is down 4,4%. I must say, to manage to spin that as a negative story for the monarchy, is a feat in itself.
These numbers are themselves reason enough to keep working towards a monarchical restoration in Romania. They show enormous potential, and a clear path forward for the monarchy, if the right actions are taken and the right combination of activity, visibility and discretion is chosen.
However, if Nicholas M-M was today a visible presence in Romania and in the Royal Family, the standing I believe would go through the roof. But that being said, what would it matter, as long as you say he shouldn't be the heir anyway?
