Greenburgh's Democratic Liberal v. Identity Divide: the James/Teachout/Maloney Primary

Map:  results of Greenburgh's 2018 AG Democratic Primary
RED: election districts that Letitia James won with over 50% of the total vote;
PINK: EDs that James won with less than 50% of the total vote
GOLD: EDS that Zephyr Teachout won with more than 50% of the total vote;
BROWN: EDS that Teachout won with less than 50% of the total vote
BLUE:  EDS (2 of them) won by Sean Maloney

Letitia James won the NY State Democratic Primary for Attorney General with 40% of the vote, prevailing over Zephyr Teachout with 31% and Sean Maloney with 25% (Leecia Eve ran far behind at 3.5%).  Teachout, however, reversed those totals in Greenburgh where she received 5258 (42%) of the Democratic vote, with James trailing with 4005 votes (32%) and Maloney again in third with 2870 votes (23% - just behind his state-wide %).  James was strongly endorsed by Governor Cuomo who won Greenburgh easily with double the vote at 8441 (67%) received by challenger on the left, Cynthia Nixon who received only 4077 votes (33%) in central Westchester's Democratic Party stronghold.  While Cuomo ran slightly better in Greenburgh compared to the state-wide, his coattails did not carry James to the lead in our town.

The September 2018 Democratic Primary exposes a divide in Greenburgh's Democratic Party between the four Rivertowns - where "progressives" Nixon and Teachout ran far ahead of their statewide numbers- and the rest of Greenburgh. As the above map shows, these results can also be viewed as reflecting a racial/ethnic gap among Greenburgh's Democratic Party loyalists as Cuomo and James (subsequently elected as NY's first African American attorney general) performed extremely well in Greenburgh's election districts with the highest % of minority voters, while Nixon and Teachout outperformed in election districts with the least minority residents, particularly Hastings-on-Hudson, which is simultaneously the most politically progressive and the "whitest" community in Greenburgh.  Curiously, Teachout also performed strongly in parts of Edgemont and Hartsdale - both areas with low numbers of black and Latin voters - where Cuomo had outperformed his state numbers. (Maloney only won the multibuilding Highpoint condo complex - which I'm assuming is the oldest ED in Greenburgh as well as a small ED in Tarrytown).    I'm not aware of any substantive policy issues that divided James and Teachout to explain this voting pattern, but I'm loath to draw further conclusions.
