Some comments at Breitbart:

MCCAIN CHIPPED AWAY at this Legacy by becoming a Bitter Old Man, a Sore Loser, and a Traitor to the country for his feud with Trump so he voted against anything Trump!

[…]

The media coverage of his funeral will be nauseating. I say good riddance to Songbird\swamp creature McCain.

[…]

Yep. Had he left the national stage after his horrible presidential run, I’d feel a lot less enmity towards him.

Anyone who’s legitimately honest will admit that it’s good that he finally died. Now he can stop screwing over this country. God knows that the only way this turd would ever leave office.

[…]

He was and has always been a traitor and will be remembered as such…

[…]

He was a backstabbing, corrupt POS. And btw- his military service was one big clusterfk.
