Kane became a pivotal point for the company during the Attitude era in the late 1990s and early 2000s, defeating King of the Ring Stone Cold Steve Austin (described as the federation face of that era) for the WWF Championship in its first pay-per-view main event.
In 2015, the WWE Triple H executive director called Kane "the constant" for his "always great" performances in the ring during his time in the company. Ric Flair instead called him the "best in the world."
He is also the wrestler with the highest number of pay-per-view appearances in the history of the federation (175). In an interview with The TaxPayers’ Alliance, Kane discussed how often politics are discussed in WWE.
Kane on the politics of the WWE locker room
“I think WWE is really a cross-section of society, and you’re gonna have everybody, and everybody talks about different things, and of course, most folks are really apolitical.
They have their opinions, but they don’t want to get involved. It’s kind of is the way it is. Val Venis was actually the guy that told me I was a libertarian, and I thought he was calling me a bad name because I had never heard it before.
Then Daniels, pretty hard left, the reason is because he’s very environmentally conscious. He’s a really good guy, and we don’t agree on a lot of the methods, but I understand where he’s coming from, he wants to make the world a better place.
And then you have folks that are much more conservative," Kane explained. Outside of professional wrestling, Jacobs has made numerous guest appearances in film and on television, including the lead role in the 2006 WWE Studios production See No Evil and its 2014 sequel.
He is also a longtime supporter of libertarian political causes. In March 2017, Jacobs announced that he was running for the mayoral seat of Knox County, Tennessee as a Republican. On May 1, 2018, he won the Republican primary election for the mayoral seat of Knox County, and on August 2, went on to win the general election.
The last title Kane won was the 24/7 Championship on September 16, 2019, the only title won under his real name. Veteran wrestler Ric Flair described Kane as "the best in the world", while Big Show dubbed him "the best big man ever"
