They all do it

Politico's Ben Smith debunks an American Spectator "report" that White House political director Patrick Gaspard held that same title in ACORN's New York office years ago.  According to Smith, it "just isn't true."

But, Smith is quick to point out, "The Spectator piece is a model of the sort of guilt-by-association Google work in which partisans of both sides specialize."

Really?  Seems to me the noteworthy thing about the Spectator isn't the "guilt-by-association," it's that the Spectator was wrong about the central fact of its "report."  Do "both sides" really specialize in that?  To the same degree?  How about giving a comparable example?

But Smith doesn't bother.  The Left and the Right are exactly the same.  Isn't it obvious?  Don't you remember all those false claims liberals made about George W. Bush being a murderer and a drug runner and a secret Kenyan?  The false claims they made about Karl Rove working for Blackwater?  No?  You don't?  Those things never happened?  Well, anyway: the Left and Right are exactly the same.
