I've said this before and I'll say it again: There are better things to attack Trump for than how he looks, what physical conditions he has or how he smells.
At face value, those sorts of things have little effect on the ability to run a country well.
Even his hair is a better target because how he wears it would appear to show vanity, a quality that might actually interfere with stable management. That's still a relatively big stretch without other evidence (of which there would appear to be plenty) though.
Attack his ideas, his intents, his politics. He makes this easy enough, right? Start there.
"LOL u smel" is something you expect in the playground. Something Trump himself might use, perhaps.
At face value, those sorts of things have little effect on the ability to run a country well.
Fuck, man, I'm not saying that the smell is necessarily a good strategic choice for winning over voters, but if it is, Biden absolutely should hammer on it. Fuck the "We go high" shite.
