That's not really how it came out. Perhaps that was Biden's intention.Biden was talking about the MAGA voters who are calling peurto ricans and immigrants garbage. Biden did not say all MAGA voters are garbage and Trump, of course, lies about it
Excellant example of why you do not wrestle with a lying pig
We're left with a comedian who says something stupid at a Trump rally and a sitting Democratic President saying something stupid. I have to say generally President's words are more important and impactful, but in this case we kind of know Biden isn't terribly articulate.
Despite the endless media spin (and your spin), most everyone knows these two mistakes are really not big deals and likely will not impact the election.
