@GottaLaff exactly. Not everyone has cognitive impairments just because they're old. And Biden is a wealth of experience that you simply can't discount.
It's about performance, and frankly Biden is performing as well as or better than any president in history. He's got a clear policy agenda for both domestic and foreign positions and he is executing it as well as anyone could with the existing Congress.
Some of that is his team. Unlike Trump, Biden DOES have "the best people".
