The charts above reflect the results of a new Latino Decisions Poll -- done between April 9th and 15th of a national sample of 606 Hispanic registered voters, with a margin of error of 3.9 points.
The most obvious result is that Donald Trump is in deep trouble with Hispanic voters. Only 20% say they will (or might) vote for him, while 69% say they will vote for a Democrat and 11% say they are undecided. That's no surprise considering Trump racist and xenophobic attitudes toward Hispanics.
What Democrat will they support? This poll didn't ask that specifically. It just asked if they had a favorable or unfavorable opinion of the leading candidates. Biden (59%) and Sanders (58%) were viewed most favorably. They were followed by O'Rourke (48%), Castro (45%), Harris (43%), and Warren (42%). No other candidate was viewed favorably by at least 40%.
