Both candidates think more should be done about homelessness and the cost of housing; specifics were lacking.
Both are in favor of legalizing marijuana.
Both are in favor of raising the minimum wage to $15.
Cuomo accepts contributions from corporation and Nixon does not; Cuomo needled Nixon because she herself is a corporation (common for actors, she said).
There was an absurd discussion about the naming of the Tappan Zee Bridge after Mario Cuomo when some (unidentified) people want to call it the Mario Cuomo Tappan Zee Bridge.
Nixon attacked Cuomo for tolerating corruption and only becoming more progressive when she prodded him; he attacked her for releasing her tax returns on a Friday (that one I didn't quite understand)..
Nixon blamed Cuomo for the problems with the New York subway system and Cuomo blamed De Blasio and the legislature.
In sum: Cuomo came across as a pragmatic politician, Nixon as a progressive idealist not so different from Cuomo when he was younger.
