3 years?
only THREE?
i would say this started in the late 80's early 90's.but i get where you are going.
and in my opinion? this may ruin them as a party,if they do not survive this ideological split,and continue to play these ruinous games..they may be finished.
2016 WikiLeaks showed the world how corrupt they had become,and i haven't see anything to change that diagnosis.
there is a growing group who are pushing back,mainly progressives and social democrats,but they are getting hammered not only by their own party but from outside sources as well.
the cynic in me says they are already done.too much has gone under the bridge to really recover.
meh..been wrong before.
