Swift having and voicing an opinion is not a "conspiracy". She should be able to, as any American, hold and feel free to voice her beliefs. Of course she might choose not to do so no matter who begs and that is also fine. There is no conspiracy here. You might or might not like it that she could do so, but others might like or not like that Tucker Carlson or Rachel Maddow can and do so.

The "conspiracy" is/was that Swift is an active psyOp warrior in the employ of the CIA and/or Pentagon, that the Super Bowl is/was rigged to get the Chiefs into the game, a game that would be scripted so that they would win. Then, in the post game celebration Swift would be whisked onto the field where she would gush in the afterglow of the Cheif's victory and then live on camera she would endorse Biden. Some additionally believed that following her endorsement Biden himself would be choppered into the stadium and appear with Swift.

Per the poll,

"Do you think that a covert government effort for Taylor Swift to help Joe Biden win the presidential election actually exists, or not?"

18% of people surveyed believe that Swift is a psyop warrior and that the Super Bowl and in fact the entire NFL season was scripted to get her into position to complete her mission. Presumably a mission now thwarted thanks to it's unmasking.
