But a leading Libertarian magazine is suggesting a new challenger may step into the ring to rival the former Tennessee governor, who is seeking his third Senate term after being elected in 2003.
According to Reason.com, "sources" have said WWE superstar Kane is considering a 2014 primary bid.
Kane—whose actual name is Glenn Jacobs—is an 18-time champion.
He's also a Libertarian and a resident of Jefferson City.
The magazine cites unnamed sources close to Jacobs, who say he's become "open to the possibility of considering a 2014 primary campaign against Sen. Lamar Alexander." The post also suggests the notion of a Kane versus Alexander primary in Tennessee is "pure rumor mill for now."
Earlier this week, Jacobs issued a challenge to Tennessee Lt. Gov. Ron Ramsey to debate the merits of an online sales tax bill currently working its way through Congress. The bill, called the Marketplace Fairness Act, has been strongly backed for months by Alexander, a primary sponsor of the legislation.
Here's video footage of Kane's 1997 debut.
