There's some element of it, but when Trump defenders must ALWAYS resort to "It's okay that he's a brazen con artist because others were," and not bothering to ever defend the substance of what he's doing, that's at a different level.
No one here, that I saw anyway, ever defended the dinner with the people that bought his meme coin, 80 % of which goes to his interests. Not one peep of why its good or even permissible. Just, yeah, he's a crook, but so are the others.
And this from people who rant and rave about Pelosi or others trading in stocks they regulate.
At this point, what will people say when Trump literally puts pardons on Craigslist? Nothing. They'll just say everybody does it so its okay.
