Correction: hate unchecked and amplified by social media wins elections. David Duke and Pat Buchanan, both notorious racists (the former being Grand Wizard of the KKK), ran for President but the mainstream media (which were once the only media most people consumed) constrained their influence.

That isn't happening anymore, and now we also have social media.

There is both Eros and Thanatos. Everything ad based (social media, evening news, YouTube, Reddit, elections) turns towards Thanatos ultimately. They used to put hidden images of skulls and other dark and dangerous subliminal symbology in whiskey ads back in 70s. Sex sells, maybe, but if it bleeds it leads.
