I don't think it says much for any argument if getting the facts right "doesn't serve [the] point".
Still, I can sympathise with the idea that Trump's chances in 2020 are better than they appear. Whether this is because they are materially better, or because he's managed to create an image of just not losing, I wouldn't care to say. In either case, I will believe a Biden victory when I see it, and not before.
And, besides, fivethirtyeight currently gives Trump a 10% chance of victory. 1 in 10 events still can happen, so I wouldn't be completely shocked if things break Trump's way just enough for him to overcome the popular vote deficit.
