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.
If you look at pictures before the leg break then you will see it's the same fake Biden. It really looks like he was replaced in Dec 2018 at Bush Sr Funeral.
