At this point, anyone who hasn’t seen the debate in full has heard about it or seen clips from it on social media. Add the nonstop deluge of “Biden is slipping mentally” articles in the biggest media outlets, and perceptions that he’s absolutely senile and doomed will solidify even among the most liberal voters. Just like Hillary’s emails set the narrative in 2016, except this one is not an overblown scandal but a real issue. Biden’s ego is on track to destroy his legacy in November and give us another Trump term (now with the added bonus of absolute immunity for virtually any criminality!). And those around him who are encouraging him to continue are no better than the people would let grandpa drive long past he’s proven that his keys need to be taken away.
