Still pure rumor mill for now, but sources close to the one-time World Heavyweight Champion World Wrestling Entertainment (WWE) superstar (among many other wrestling honors) who goes by the name "Kane" tell me that Glenn Jacobs (Kane's legal name) is "open to the possibility of considering a primary campaign against Sen. Lamar Alexander" for the Tennessee Senate seat Lamar! has held since 2003.

That's a whole lot of caveats and no announcement from the man himself, but it would be one of the more delightful GOP primary battles for the libertarian-minded to watch.

As Matt Welch blogged here in 2010, Kane considers himself libertarian, has been active with the Libertarian Party in the past, and has lately been a loud public voice against the Internet sales tax.

Kane's wiki.

Jonathan Rauch at Reason back during Lamar!'s 2000 campaign presidential run reminds us why he's a good guy to get out of the Senate.
