Trouble is, not that many people know who Gordon LIDDY is?

[Rosa Luxemburg]

Kudos to Letterman for mentioning Liddy the plumber! McCain was embarassed! However, not that many people know who Liddy is. Just another of those crooks that McCain pals around with?

Liddy's connections to John McCain
In 1998 Liddy hosted a fundraiser at his house for John McCain's re-election campaign at which guests could have their pictures taken with McCain and Liddy. Over the years, Liddy, who has referred to McCain as "an old friend," has made at least four contributions totaling $5,000 to the senator's campaigns -- including $1,000 in 2008
