First of all- I agree concerns about both their ages are very much valid here but hasn’t Biden had a stutter from a very young age and struggled with it most of his life? Surely we should cut the guy some slack here?

That said, of course there won’t be slack. Political debates (especially one of high stakes as this one) are cut throat and no one has room for error.

Go back and watch his 2020 debate footage or his VP debates. This was not his stutter.
