This is, of course nonsense. The data is clear that Latinos vote majority Democrat, though it was a smaller majority in this election than the previous.
Citation needed. A lot of the Latinos I know in NYC voted Trump. A few were Democrat voters who grew tired of being insulted by Democrats who casually lump Latinos into a big "left loving Latino pool" when they are Puerto Ricans, Dominicans, Chileans, Ecuadorians, etc; Individuals with distinct cultures and backgrounds. Latinos are also heavily religious which is very influential as well.
