Except Trump's lies have a nasty habit of coming back to bite him in the ass. Unfortunately not permanently, and unfortunately not for very long. But they undoubtedly do.
It cost him 2018 and 2020, got him nowhere in 2022 and it could cost the GOP 2026 and whoever the next republican presidential candidate is in 2028.
Because just like the trolls, their only claim to legitimacy is that Trump "won." It doesn't matter if he lies, it doesn't matter if he doesn't know what he's talking about, it doesn't matter if all his prognostications come to not because he's a liar who doesn't know what he's talking. They don't care about that.
It's a team sport for them. They don't care if their players are constantly running up against the refs and getting flagged, they don't care if they're injuring or fouling the other team, they don't care if the coach is a drunk and running around on his wife with a cheerleader, so long as their team still wins.
As always, the best course in "dealing with them" is defeating them politically. There's no use reasoning with them, the only course of action is to render them politically irrelevant.
