On a popular US poll twitter account, I found an interesting phenomenon. (Similar thing also has been happening on other US poll twitter accounts.)
Most of the polls it has (re)tweeted are favoring Biden by 10% nationally or so (except those conducted by https://twitter.com/Rasmussen_Poll). But all the polls which it itself conducted on twitter in past months always show 30%+ lead by Trump, and the most recent one is https://twitter.com/PpollingNumbers/status/1310007036294430725:
At least half of comments under the tweet are anti-Trump or pro-Biden, and so are half or most tweets on Twitter in general. My impression has been that Twitter is a social media with majority accounts having (neo)liberal ideology. I was wondering how to understand the contradiction which happens consistently and is echoed by another user? Is it because of the silent majority and shy Trump supporters on Twitter? Or is it because of interference by Twitter accounts outside US?
