A Democratic Socialist, Alexandria Ocasio-Cortez, defeated an entrenched democrat, Joseph Crowley, in a major upset in the primaries. She put her finger on one of the reasons why Trump won:
“What I see is that the Democratic Party takes working class communities for granted, they take people of color for granted and they just assume that we’re going to turn out no matter how bland or half-stepping these proposals are,” Ms. Ocasio-Cortez said in a recent interview about why she was running.
There's a reason why, as different and Trump and Bernie are ideologically, there is overlap in their supporters--and I think these types of upsets are just beginning.
As they say in Les Miserables: Do you hear the people sing--singing the song of angry men?
