The contents of Hunter's laptop didn't stop me from voting for Biden, but that's because I'm a cynical jerk that already thinks politicians are corrupt by default.
How about this: you don't get to decide what's remotely important to people in the context of the election?
"The Hunter Biden story is insignificant" is a judgement, not a fact, it's a judgement. I'd say that calling it "misinformation" is bizarre, except that most prominent allegations of misinformation boil down to judgements too.
