You are entitled to your opinion, but remember these are your opinions. Facts are things proven beyond doubt. Your wording and tone suggest you believe there is no doubt and you are presenting something everyone should see. Nope.
You call it a cover up, but the truth is that even today the word on Biden's condition is subjective. He is a life long stutterer and it is something he's had to work to overcome all of his life. He automatically is working at a disadvantage with his speech. The pauses and gafes are nothing new. They were just easier to hide or control when he was younger. It's a fact that people slow down as they age. I can assure you anyone near 80 years old is not going to have the same reflective abilities as a 50 year old. But one thing aging and slowing down does is not treat all people the same. It's going to show more with someone who has other underlying conditions. For example, asthma is something that is well documented as harder to control when we are babies and when we are older. But when we are young and healther, many can control it better. Same goes for speech impetiments.
There is no question Biden is not as sharp as he used to be. But the extent of his condition is subjective. Some think he's worse than he is. Some think he's better than he is. Very few of us who think one way or the other are actually doctors or have any qualification to make the right call. And, keep in mind, doctors often don't always agree with each other. Why? Because there is so much more in the medical field that even the professionals are still trying to figure out.
Regardless of Biden's condition and whether he is fit or not to be President, what became clear is the very question of it was hurting his chances at winning. The Dems saw this unfolding and knew if they wanted to have a chance they needed to act. They surely did a deep data dive to see what the path was with Biden vs. Kamala and came to the conclusion that they had a better chance with Kamala. And you know what? They actually got that right. Kamala is already polling better than Biden.
I say all this as someone who refused to let go of Biden as a candidate. I wanted their unwavering support for him. And, I can now say, I was wrong. I'm glad they persuaded him to step aside. I am glad despite how difficult it was for Biden that he made the right choice. Why? Because this is not about Biden. It is not about Kamala. It is not even about Trump. It's about what they as candidates stand for and how that lines up with what we stand for. Just like I quickly got behind Kamala, most Republicans would quickly get behind the next man or woman up if Trump was not the nominee. Trump was not just chosen because everyone loves Trump. There are plenty within the Republican party that wish it was someone else. But they know Trump gives them the best chance, so they stand behind him.
So yes, what you posted is garbage to me.
