I certainly hope the Dornsife poll is accurate as of today, and Trump wins by 6 points or more. But there is no way he breaks even with Hispanics. That has never happened since the Hispanic vote became large enough to matter, and so long as mass immigration persists, it never will happen. Most are natural Democrats.
Considering the extreme media bias against him, Trump would do well to win a quarter of the Hispanic vote.
Most male Hispanics are not voting for a woman President.
