It's because he's had so much plastic surgery the past 8 years he looks completely different. Go look at pics or videos of Biden from 2016 while campaigning for Hillary or while as VP and compare them to 2020 or 2024. Almost unrecognizable. His earlobes are now attached when they weren't before. Very bad plastic surgery.No Marv. The easy answer is not that Trump truly believes Joe Biden died in 2019 and a body double/ clone served out the last four years.
That would mean he’s a paranoid schizophrenic.
