Google's algorithm is biased toward recency. In a universe of "Foo Badbar", "Foo Neutralbar" and "Foo Goodbar" -- If a person searches for "Foo" after there's a bunch of stories in the press about "Foo Badbar", the results will all reflect that topic. For something like "Latino", it's crazy for all the results to reflect the border wall and not at all controversial for Google to want to promote "Foo Neutralbar" and "Foo Goodbar" to balance the results.
