Ya well Biden isn't exactly 100%
Honestly, I agree. I think that he might actually have some cognitive issues. Though, I doubt he actually has
dementia, which would be an extremely dangerous situation for the country obviously. Because he definitely couldn't be trusted to make rational decisions in office. The good news is that there's no evidence of him actually getting demented. He does often get flustered, and he does have a way of seeming confused at times. However, this doesn't happen in all circumstances. People in the early stages of dementia can have episodes caused by the neurological problems at any time. Biden seems to only have issues with forgetfulness when he's flustered.
Most people with dementia wouldn't really get flustered per say. For instance, someone with dementia might forget what they were going to say. They might even realize that they forgot. Then, they might start thinking "I keep forgetting things" and focus on that. What the person usually wouldn't do is think "Oh boy, I know what I was going to say. I'm going to remember, I just need to keep trying." This is exactly what Biden does during his "gaffes". Probably, what's happening with him has several components. One is that he's obviously under a lot of pressure, and the other is that he used to be a stutterer. I saw him stuttering during one of his gaffes as well, which isn't surprising.
It tends to be an ongoing issue, and it's something that happens when a person gets emotional and kind of tripped up by a situation essentially. As he's gotten older, he probably finds it harder to remember things and snap himself out of it when this happens, because one's memory declines somewhat with age even without being compromised by dementia. Despite this, there are situations where I'd wonder if his performance could be affected. If something came up out of the blue and it was crucial to respond right that instant, I'm not entirely sure how well he'd perform. He might end up handling the situation very well, or it could be a disaster. It's hard to say.
He's the type of guy who needs time to think about things. Fortunately, most critical situations that would come up in office would give him at least some time to think about the situation and formulate a response. Even it was a really high pressure situation where it was the middle of the night and he had 5 minutes to decide what course of action to take, he very likely would handle the situation well. What can be an issue is if he's debating someone or is asked a question and has to respond with the right words, right in that moment. That's when he gets tripped up and has a gaffe. Trump is kind of the opposite. For him, taking time to think about things is very much not his strong suit.
He often doesn't really take much time to think things through. He's impulsive and does stupid things, because he hadn't taken the time to think about it. He's also overconfident. Even if what he's saying is inject disinfectant level dumb, he'll never admit to being wrong and just wait for people to forget about it basically. Or just do some other crazy thing to distract people. I think I'd rather have a guy in office whose the type of person who thrives on thinking things through as opposed to snap second decisions than someone whose very quick on their feet but doesn't think things through, is extremely overconfident, and is extremely self centered, arrogant, and has a tendency to act aggressively.
To me, Biden is not an ideal president, but at least he's sane and level headed. Also, he is a pretty bright guy I think, given that he got elected into the Senate all the way back in 1973 when he was in his early 30s. Though, I have to say that I don't entirely like the fact that he's the definition of a career politician and has essentially been in Washington for his entire adult life. I think it would be nice if someone who is more of an "outsider" actually came into Washington with a solid platform and knew what they were doing. That's what REAL democracy would be. It is true that the Washington "insiders" have interests that are very different than those of the people, and we're all sick of that.
However, in order for that to happen, we'd need at least three parties. Because then you could have Democrats, Republicans, and another party that's created for people who aren't corporate elites and/or Washington insiders. If such a party existed, I'd choose that one over the others 100% of the time. Though, no such thing exists. So, I honestly feel like the entire election was just choosing the lesser of two evils. I do think that someday, we'll have a president who isn't a super wealthy political insider who has been in Washington for decades and decades. But IMO it's better to stick with the status quo than bring in an outsider whose a crazed egomaniac.
