A lot of it comes down to immigration disappointment. Some people expected major reform and felt let down when deportations stayed high under Barack Obama.
Yes, because they voted for him based on the idea that he would open up immigration for them.
"After the economy,
the issue that mattered most to Latino voters was immigration. What does Latino voters’ strong support for President Obama mean for the future of immigration reform? President Obama
told the Des Moines Register in October that he was “confident about immigration reform in the second term.” Shortly after the election, House Speaker John Boehner told reporters regarding immigration reform, “it’s time to get the job done.” It is clear from national polling data that there exists support in both political parties for such action. According to a
national exit poll conducted by Edison Research, voters, by 65 to 28 percent, said that most illegal immigrants working in the U.S. should be offered a chance to apply for legal status, rather than be deported.
Whereas Democrats polled 79 to 14 percent in favor of legalization, even a majority of Republicans support legalization over deportation (51 to 42 percent). Of the ethnic groups profiled, African Americans most strongly supported legal status for undocumented immigrants, by an 81 to 12 percent margin. This is even a greater margin than among Hispanic voters (77 to 18 percent), perhaps reflecting African Americans’ long struggle for full legal status, including the right to vote, in our country."

It was a simple choice for them back then, which did not pan out for them. Does not change the fact that they still come from very racist cultures and countries.
Edit: Also notice how our people supported them even more than their own people.
