The Demise of Italian Extra-Parliamentarism
I think the reasons why Renzi lost this referendum are complicated.
From my impression, during the campaign before the referendum, too many resources were spent by the party of the former Prime Minister Matteo Renzi in order to promote voting for changes of the constitution. We had a lot of advertisement on Facebook, YouTube, Twitter, Instagram, on the radio and television, in the streets - everywhere. It was stressful propaganda to force people to vote "yes".
