Did he kick a guy on the ground or was it a standing head kick. If the latter that’s pretty impressive for a politician.
Victim was sitting.
It was just a downward slap with the bottom of the foot while the guy was sitting. The kicked fellow was able to stand up, so no damage. Not much room for a real kick, except maybe an axe kick, which if properly executed, could have compressed the spine, crushed the skull, and spurted brain matter out the ears and eyes.
