I think for someone as advanced in age and tired as Biden is, he needs a truly inspiring VP candidate. He stepped up when we needed him and beat Trump, but Biden also needed to be a one term president as a stopgap for the next generation, but like every other Democrat politician, he’s hanging on too long, and we’ll pay the price.
I get they tried this with Kamala Harris, to some extent, but she has squandered the opportunity. I’d consider myself fairly well informed, above average for sure, and I’d struggle to name 5 things she’s done in the last 3 years.
