Sore Spot?

At an event upon which he insisted
He struggled to do unassisted
Take a sip from a glass
Not fall on his *ss
His explanation was so very twisted
 
By his frailty the press was perplexed
By their reports Trump was quite vexed
600 salutes
Leather-soled boots
Was his lengthy and crazy pretext
 
“A weak man, I surely am not!
On part of the ramp I did trot.”
20 minutes he raved
that he’s strong and brave
Do you think that we hit a sore spot?
