Why are you being so needlessly hostile?

A lot of hispanics voted for Trump in this election.

It would be ludicrous to think that, all other things being equal, they, or any other group of people, would switch their pick due to being victims of hyperbolic propaganda such as the one described.

Pretty sure Hispanics can think for themselves, with factual references at hand. I believe the linked article paints them in an unfairly gullible light, while it does nothing to discredit what it claims as being conspiracy theories. They point to current developments happening in their home countries, only becoming discreditable 'theories' because of the absurdity in which they are framed (in the article).

To name an example, The Open Foundation (associated with philanthropist Soros) has been funding parties and congresspeople all over S.A. who are looking to advance certain social causes. This is part of funding declarations by the recipients, and since it's not unlawful, and not a secret, it's not a conspiracy; and since it's not fiction, it's not a theory (in the sense of supposition). One of such causes is the decriminalization of abortion, an issue that's been traditionally (fiercely) opposed.

Considering Trump's aim to defund Planned Parenthood, and the appointment of a fitting (Catholic) judge to the Supreme Court, couldn't they not lean towards him in this aspect on the grounds of a proven track record, rather than just propaganda?

Well more people in California voted for Trump than Kentucky and Tennessee combined.

This is primarily bacause California has a much larger population. You can add North and South Dakota in this group as well.

What does that have to do with anything?

It explains how most immigrants can vote conservative with the state still easily remaining liberal overall. Read the fucking context.
