They say "perception is reality". Not always valid. But if you say or show it enough it becomes reality. In some case maybe so. We have AGE held against Biden, but why not Trump ( a few years difference). Oh, 'perception' says so. Physically, Biden shows hampered walking while Trump displays energy (negative ranting at rallies). 'Perception' says Biden too old, Trump viewed as younger. Do we factor in 'mental acuity' and aging? My real perception would suggest that from the shoulders down Trump is younger, but above the shoulders Biden's cerebral dwarfs Trump. I'll take above the shoulders.
