Biden voters were asked in a large poll whether they still stand by their choice or if they regret voting for Joe Biden.
Take a look at this short contribution from SkyNews Australia.
So a Twitter account has even been created, called Biden Voters Posting Their L's Online, and it now has 204.600 followers. Of course there are also Trump fans among them, but it actually seems that this was used by Democrats, who are sincerely sorry. People who were equally blinded and probably not properly informed and misled by the media. Now the monkey comes out of the sleeve.
Also on Reddit and a number of other platforms is Biden Voters Posting Their L's Online active.
The regrets' Twitter account:
