I remember an old story where Peron was once asked about political plurality, he said:
'we have a lot of political views in Argentina, we have people from the center, from the left, from the right, from the extreme left, from the extreme right'
And what about Peronists?, asked the interlocutor.
'oh no, they are all Peronists' answered Peron.
In other words it is a political label devoid of any consistent ideological basis other than some sort of Machiavellianism; striving only for power and self preservation it is realpolitik incarnate.
Thats how it looks to me anyway.
