Why is McCain so "Tight-Fisted" when he gives a speech?

Question

I noticed he always seems so rigid and tight fisted, like he's really angry. But he tries to hide his anger by smiling a tight grin.

Is that normal?

Answer 1

if you watched the news at all you would know he was tortured for 5 and a half years. when his jet was shot down he broke both arms and it went downhill from there.

Answer 2

It is his injury.  He can't move his right hand very well and he tends to keep it in a fist. You may notice that he makes an effort to shake hands with someone.  He almost grimaces at times.

Answer 3

I bet if asked about this, he'd play the POW card...  

Answer 4

It goes along with PTSS and the physical injury that occured when his plane went down. We should honor his service but also realize the guy is a few cards from having a full deck.
