Progressives and Far Left Start War With Democratic Elites

Ocasio-Cortez Leads Protest Against Democrats after she lead a sit in at Nancy Pelosi's office. Many people were left wondering why the newly elected representative would protest democrats over climate change instead of republicans.

Nancy Pelosi supports climate change legislation so why are far left activists protesting her? More importantly, why is Alexandria Ocasio-Cortez protesting he fellow Democrats?

It seems like internally and externally Democrats are facing a new challenge with far left activists and candidates. Meanwhile we can see Kyrsten Sinema winning in AZ even after she said she supports 60% of trump's agenda.
