It's funny how easy it is to parse this issue.
Democrats have openly talked about the utility of someone like Taylor Swift being able to convince their fans to vote dem.
Both Dems and Republicans have used celebrities to "get out" the vote.
Swift has aggressively pushed for democrats on her social media in the past.
Swift has millions of rabid fans that are obsessed with her and have said they will vote however she tells them to.
It's not a stretch in the slightest to think that someone representing a prominent democrat or Bidens admin has approached Swifts people to ask for her support heading into the campaign.
Maybe it has happened with Swift, maybe not. It's not a stretch in any way to think a celebrity could be approached by either party for their influence. It would actually be naive to think this sort of thing does not happen.
