Not physically possible
ZH features a semi-scholarly article on Google's biased autocomplete. Not news. Google is Soros, and its autocomplete has always made it harder to find non-globalist TROLL. But in the specific case of Trump vs Hillary, I can't blame Google. It's just physically impossible to make an unbiased search algorithm.
Trump is totally and OFFICIALLY hated by ALL paid writers on ALL subjects. Every article on every subject and every comment on every subject includes at least one Tourettespew of venom against Trump.
If you pick up ALL web content for any given day in the last 12 months, you're going to find anti-Trump sentences in 90% of the pages on all subjects. The pages that don't contain Trumptourette are autogenerated 'error documents' and similar mechanical stuff. All human-written pages are anti-Trump.
I'd guess only 0.001% of all web pages have ANY sentences relating to Hillary, and of those few, exactly 100.00% are glowingly positive.
No filter can undo such a wild overbalance. Anti-Trump statements are in the same frequency range as THE or AND.
