Why doesn't he just go "a vote for me is a vote for Kamala" like a good octogenarian instead of trying to fool everyone into thinking he will last another 4 years...
Why doesn’t he just go “a vote for me is a vote for Kamala”
Because the US electorate is both racist and sexist. Reminding them that if Biden dies or is incapacitated that the country would be taken over by a non-white woman would probably drive votes to Trump. If his VP was a white protestant man, he could probably get away with reminding people how good his VP was.
But, I do think you're on to something in that his focus shouldn't be on himself, it should be on his team. Tell voters that Trump is a narcissist, that his cabinet will be full of ass-kissers. Remind them of how many of Trump's cabinet were yes-men and still got fired because they didn't kiss his ass enough. Show how they did essentially nothing over 4 years despite control over the house and senate. Then, contrast that with the effectiveness of his people. For example, how Trump talked a big game, but accomplished nothing. But, Biden's officials are actually suing the big tech companies for abusing their monopolies. A lot of the things Biden's picks are doing are wildly popular among the American people, but most people aren't aware of the accomplishments.
