My experience is with great resentment towards Latinos by blacks. They are perceived as taking away their share of the pie. I have witnessed entire apartment complexes emptying out of blacks when Latinos start to move in. There is no love lost here folks. The democrats will have a hard time juggling these two groups, which happens when you play racial politics.
We used to have a black area of town. Had been that way for the last 60 years I can remember. Went through there not too long ago and all the markets, stores, etc. are now Mexican. Mexican women with their children pushing a baby stroller walking down the street. They have moved the blacks out and replaced them.
