WWE legend Mick Foley says he couldn't be more proud of his good friend Kane for becoming the next mayor of Knox County, Tennessee ... saying, "I think he'll do a great job!"
Foley campaigned for Kane -- real name Glenn Jacobs -- touting his friend's longtime interest in politics and the fact he's a super smart dude in real life.
So, when Kane won the election this week, Foley wanted to assure the people of Knox County they're getting a winner!
"He's a very wise man and caring person, and I think he'll do a great job in Knox County."
He also had a pretty emotional message for his friend -- it's good stuff.
