I’m not saying the X algorithm is biased, nor have I conducted any research. This is just an anecdotal observation. I follow both Donald Trump and Kamala Harris, but I never see Kamala Harris’s posts or content related to her on my ‘For You’ page, while I frequently see posts from and about Donald Trump. I occasionally check her account or search for her explicitly, so I would expect the algorithm to show me more posts related to Kamala Harris.
