Yup.
Don't get me wrong, Biden was showing his age moreso than Trump specifically in terms of his voice sounding increasingly frail (particularly in that awful debate).
But in terms of the content of his speech, knowledge and understanding of world events and behaving appropriately, he behaved far more appropriately than Trump.
Biden was a competent statesman showing significant signs of aging (to the point where, even if he could still do the job competently, optics made him a poor candidate). Donald Trump is, and has always been, an ignorant, self-centred man-baby, lacking the intellect, curiosity, temperament, ability and even the desire to adequately discharge the duties of the office.
