Obama broke the GOP. Their civil war has lasted almost twenty fucking years. Even now, all of this is revenge for Obama winning by a landslide, and supported by a hell of a lot of white voters.
Hispanics, in my experience, are deeply prejudiced, self-loathing people, especially older Hispanics. They tell themselves that whatever ethnicity they are, whether it be Venezuelan, or Mexican, or Puerto Rican, that that ethnicity is better than those others - and usually those others are either more black (Dominican, Cuban) or indigenous (Guatemalan, El Salvadorian). I don’t know if Caucasian, Black, or Asian people feel the same way about others of their own race. Hispanic people usually even share a common language, religion (Catholicism), and elements of culture, but they all hate each other. It’s not surprising to me that so many of them are breaking for Trump and that they relish the idea of other Hispanic people being forcibly deported…until they are deported, too, of course.
