[True, I have to begrudgingly give her that. Another “nobody” almost took down the establishment candidate.]
At this stage, within the Democratic party in NYC, my guess is it’s blacks and Hispanics vs Asians and whites, with blacks and Hispanics gaining ground for demographic reasons (i.e. immigration and birthrate disparities). In time, I expect more Asians and whites to move towards the GOP for purely economic reason as Democratic pols trend black and Hispanic, and push for big tax and fee increases to pay for expanded welfare programs and subsidies. Ethnic politics will take center stage. What was once old will become new again.
