Palin blacked out McCain's name with a felt marker recently, saying she is fond of McCain but wanted to travel "incognito."
McCain said Sunday he has no problems with the blacked-out name and he and his wife Cindy remain close to Sarah Palin and her husband after the presidential campaign.
"She is going to be a force in the Republican Party for a long time," he said. "And the hysterical attacks on her from the left continue to validate that."
But he jokingly questioned discussing Palin's visor when there are much bigger issues like climate change and health care to talk about.
