They don't sound the same either. Now I presume it is possible that president Biden is the same guy as VP Biden, after plastic surgery, as there really seem to be some scarring that would result from that. Or the plastic surgery has been to change some actor into looking a bit more like the VP guy. Or there are masks being used, or even more than one actor. I don't really have any sure opinions, let's just say that I would not be too surprised if the current president really turned out to be an actor, or a couple of actors, as he or they really look quite different than the VP did. But admittedly plastic surgery can also cause that.

I just think that if there are suspicions about something like that, these days, when DNA can be used to identify a person, it should be possible to demand that when such suspicions happen that they can be tested with DNA sample, and do the sample taking on live feed, with the sample then taken to the lab through the kind of unbroken chain that is used for criminal cases so it would be possible to actually prove, without a doubt, that the person is the one he claims to be when the person in question is in such a position, with such power at his disposal, as the president of your country is. Maybe make it mandatory that samples will be taken when somebody first enters politics so it will be possible later to verify that there have been no switches at any point, and the person is who he claims he is.
