In recent history 'proggressive populists' have a bad track record..........
Blair, Hollande, Obama, Trudeau
What's in common: all were elected as progressives then all of them just spend/spent their time fecklessly rearranging the deck chairs on the titanic: actively creating social license for wars on Iraq, Libya and time bombs like the tar sands and protecting (& then joining) the swindlers ruining the economy.
Even poor little Syriza in Greece was hijacked by the EU and in the end betrayed their populist supporters.

Result: Brexit, Trump etc  ... and unless some progressive populists win and become effective in office - somewhere - it will get much worse.
