To be honest, I haven't really been watching WWE lately (mostly been focused on NJPW and ROH), but I was shocked to hear that he even came back recently. Running for office while wrestling seems a little strange, especially as a character like Kane, but he must still love doing it if he's back again.
It's weird that winning the World Heavyweight title was seen as his thank you run, but that was more than 7 years ago now.
