Such sentiments continued even a couple years after the election: https://www.reuters.com/article/us-usa-trump-russia-poll-idU...
Let's also not forget that the Democrats formally challenged election results in 2000, 2004, and 2016 - all the recent presidential elections they lost: https://www.nytimes.com/2021/01/06/opinion/democrat-republic...
Your fourth link is misleading. You've picked a link from a moment in time when Barr had released his summary of the Meuller report but Meuller's criticism of Barr's summary as being inaccurate had not been released.
As for the fourth link - I am not sure of the timing of that particular poll (I just pulled that from a search earlier), so I'll have to take your word on that. Thanks for pointing it out.
