Biden, or whoever it is, appears to have had a lot of plastic surgery....a face lift, glassy look to his face now....but one thing I've stumbled upon when comparing photos is his ear lobes, sometimes loose, sometimes connected...not something changed with plastic surgery.  I get how it's possible to use body doubles, but I don't know how you can match a voice. I guess anything is possible. Compare Biden's ears on your photo vs. the new Biden....  https://gcs.thesouthafrican.com/2020/02/80432ecc-063_1207589215-1200x858.jpg
