I think this is an interesting point that I didn't really notice until you pointed it out. I'd like to see more posters respond to this point.
They should, but they won't.
They're too busy peddling their defeatist narrative and thinking that 2020 is somehow automatically a lock for Trump because of headlines like this without bothering to look at the finer details.
They think Trump won in some incredible landslide that makes any hope of him losing completely moot by default. Never mind just how historically unpopular he is despite the economy being good right now.
They accuse the right of using mental gymnastics to pursue their narrative when they don't realize they're doing the exact same thing, only for a defeatist narrative. They think Trump is this invincible, monolithic thing that will win no matter what despite so much evidence that shows that the contrary is also very possible as well and even more likely.
That's why when threads show up showing Trump gaining even a little support, they automatically assume it's true. But when threads show up saying Trump is losing support and Dems are gaining traction, THAT's when they start questioning it. Hell, they don't even do that. They just automatically assume it's wrong because 2016!
It's lazy, it's dumb, and it's just so damn headache inducing.
