Why do blacks support the Democratic party in higher margins than other marginalized minority groups

Well, the voting habits of religious people is another subject, but people of faith don’t tend to fall for the political fad of the day. The less religious northern European countries are more prone to ideological fads.

Nailed it, the GOP makes it clear every chance they get that they think blacks are lazy.

I think it has to do with slavery. That is so fundamentally part of the American black experience that anything harkening back to that time is sure to be met with a kind of physical revulsion that cannot be explained. The GOP is the only party who reminisces nostalgically about those times, talks about the Confederacy like it wasn’t racist, and pretends that barriers to voting, demeaning blacks in the media, and making difficult their participation in our democracy isn’t racist. Other groups have suffered alongside black people, but they don’t have the history, either in length or severity, to feel those on an almost subconscious level.

you know great grandpa always said teddy Roosevelt was the last true republican and Wilson was the last true southern democrat

Interesting comment. I could argue that LBJ was started out as a true southern Democrat, but he obviously changed along the way.

The “war on drugs” has hit the black community especially hard and that was Nixon’s baby. But overall, I think it is the dog whistle politics that explains the adherence of blacks to the democrats. Not much of a dog whistle actually since every seems to hear it.

On a purely political level, it helps that Latin American states generally have robust and at least nominally left-wing political parties. The PRI dominated Mexico for decades, while the Central American countries from which more recent migrants come from such as El Salvador or Guatemala had extremely polarized political situations with violent clashes between the Left and the Right.

A “little to the right” in what sense? Certainly not on socioeconomic issues considering blacks and Hispanics are lower income then whites and thus much more likely to support welfare programs. Even on cultural issues, general societal shifts on non-abortion issues probably cancel out any greater cultural conservatism on the part of these minorities. It’s true that they generally haven’t supported liberal insurgent candidates but that’s because most of these insurgent candidates before Sanders ran more on cultural progressivism and opposition to war (someone like Howard Dean comes to mind) rather then socioeconomic populism designed to appeal to college students and white progressives rather then the multiracial working-class. The few Democratic insurgents who did real outreach to blacks and Hispanics and focused mainly on socioeconomic issues saw considerably more success with them such as Robert F. Kennedy, Jesse Jackson (who was black himself obviously), and Bernie Sanders. While a majority of blacks and Hispanics certainly didn’t vote for him, Sanders made significant inroads with both especially the latter towards the latter half of the primary cycle if one looks at the microdata. For example, he won CA-40 and CA-46, both of which are urban, majority-Hispanic districts.

I think the lack of a Spanish far-right has more to do with bad memories of the Franco dictatorship then anything else. Neighbouring France and overwhelmingly Catholic Austria have some of the strongest far-right movements in the Continent.

Which countries and ideological movements do you have in mind specifically?

Neither Cruz or Rubio is leading the Republican Party.
