Think about it. We should be able to tell when he was replaced. Was it before Covid? When was the 1st time Trump said he wasn't the same person. The earliest I can find is Jun 2019. Which would make sense because they cheated in 2018. We can look at pictures & video broadcasts to help find dates.
Any one want to help here? Lets do some research.
Update: Looks like it happened right after Bush Sr Funeral in Dec 2018. There are articles about Biden going under plastic surgery at the beginning of 2019. All the photos don't look like him after the start of 2019.
I kinda remember him looking different during hussein's reign of terror. Goes from that perpetually zonked-out mongoloid skull to what we know today. Maybe the real birth Biden died from something before Trump's first term, but they couldn't afford to lose all the connections with Russia, China and Ukraine.
