Trump has a habit of being imprecise in his language and this is why they accuse him of lying.
For example, during the debate Trump said some Democratic states execute babies after birth. This is not true. But what is true is some Democrat states prevent doctors from saving babies delivered during failed abortions. They do not require doctors to take any measure to save babies that are alive after the abortion attempt. This is not technically an execution, but I suppose you could call it that.
Trump also said, "every legal scholar wanted to overturn Rove v Wade". Again, this is not true obviously, since many scholar have opined negatively over the decision to overturn Roe. But many legal scholars have stated that Roe v. Wade was bad legal reasoning. Among them was RBG. Not all wanted it overturned though, but I would argue that was more political than legal scholarship. Had Trump said many instead of all, it would be a reasonable statement.
Almost all of his lies fall into that category. There is some truth to what he says, but the way he says it leave him open to attack.
Biden's lies are just flat out lies. Like his claim he inherited 9% inflation. Simply wrong. His claim no soldier died during his administration is also a blatant lie. Much worse than the one they claim Trump told when he said there were no terror attacks during his admin.
The thing is, all politicians lie and Trump knows it. So does Biden and so do the media and Democrats. They were lying about Biden's mental health, and they still are.
This is about how I see it. Trump's hyperbolic and imprecise language leaves him open to "misinterpretation" that sends the NPCs into a frenzy. For those who are fairly well informed, figuring out what he was talking about and trying to say, is usually not too difficult. However, for those who believe the kind of things like "Trump said to drink bleach," anything he says has to be taken to the worst possible extreme.
His strength in a debate is that he's relaxed, confident, and not afraid of a fight/challenge. He's still not a great debater though. He can be very repetitive, gloss over important details, and misses a TON of opportunities. But, smart people don't really focus on debates to decide who they'll vote for.
Smart people do research. Smart people have principles that they've thought (and prayed) about, and vote based on those principles and ideas. They don't have to be tied to a specific person. They can feel free to vote for the person who is most in line with their principles and ideas at any given time.
A smart person also doesn't let stupid and inconsequential nonsense dictate what is best. NPCs and irrational people (aka leftists) do that.
Biden on the other hand is an avid liar. He gets off on making up BS. He can't handle a challenge. His response to people not agreeing with him, or things going his way is to get dismissive, get angry, and then lie some more. This is not something new with his mental decline. Now, he just glitches when his brain tries to process all his nonsense and respond to it. While it amuses me as a conservative, that understands the terrible things he's done throughout his life, to see him fail so hard, but as a Christian, I feel sorry for him and the abuse his terrible wife and those around him are putting him through.
