For all I can tell

Political bloggers are all abuzz over what Tennessee Democratic Party Executive Committee member Fred Hobbs (note party affiliation) has to say about Barack Obama:

“He’s got some bad connections, and he may be terrorist connected for all I can tell. It sounds kind of like he may be.”

Political discourse is great, isn't it? Thanks to his excellent use of qualifying statements, there's no way to logically argue with any of that.

Because of such wonderful phrases as "It sounds like" and "for all I can tell", it is absolutely impossible for any of the following statements to be proven wrong:

Fred Hobbs may be a member of the Illuminati, the Priory of Sion, and NAMBLA for all I can tell. It sounds kind of like he may be.

It sounds kind of like Hillary Clinton keeps a copy of Mein Kampf by her bedside. For all I can tell she might be a Nazi.

For all I can tell, George Bush might well have summoned Hurricane Katrina with his black magic. It sure sounds like the sort of use he'd find for his wizarding skills.

It sure sounds kind of like Randall Shelton, in Mrs. Glenburg's second period trigonometry class, has no friends. He sleeps in a barn and never takes a shower for all I can tell.
