Which doesn't need to be anything about a "CIA psyop". I believe the above is (or could very realistically be) the case, and I could very well answer "yes" to that, without any "CIA psyop" need be involved.

In other words, that people from the Biden administration and PR team, working to get Swift to endorse him publicly, and perhaps do a few stunts with him (with or without an exchange of money or favors involved), for the obvious election marketing reasons.

That's not the same as a conspiracy in the "illuminati" or "CIA is behind this" sense (as it's made to be), nor is it the same as just "Swift having and voicing an opinion".
