I went through the motions of checking that this was real, even though really I already knew it was.
Any Christians who continue to support him at this point are probably self-declaring themselves to be part of an entirely different 'religion' altogether. As of early this year, Trump still broadly retained the support of over 40% of America's White Catholics, if this and the latest episode with the Pope, which has been coming, doesn't convince them they are misguided then it's hard to fathom what will.
Probably best that no one tells Trump that you don't actually have to be an ordained priest to become Pope; he'll be invading and installing Vance in the role. He'll then be halfway through the V's and can turn his attention to Vanuatu as presumably he'll once again be giving Vietnam a swerve.
