&gt; I hope you are joking. Popular&#x2F;big subreddits are astroturfed like crazy and often have mods devoted to controlling the narrative. Example: you&#x27;ll have to search long and hard before finding anything positive about Trump in r&#x2F;politics.<p>Astroturfing definitely explains the heavy Sanders biases at &#x2F;r&#x2F;politics, but the anti-Trump bias there doesn&#x27;t even require astroturfing. Reddit is overwhelmingly left-leaning, significantly harder than the general public. Add that to the fact that Trump doesn&#x27;t even do well in the general public, the anti-Trump narrative in &#x2F;r&#x2F;politics isn&#x27;t even surprising.
