The Left isn't obsessed with destroying Karl Rove simply because they want to taint President Bush by taking out one of his closest confidants. When they're not focused on their fantasy that Vice President Cheney is the de facto president, they sometimes think Rove is. To destroy Rove is to neuter the Bush presidency.
As resolute, effective and visionary as President Bush has been in office, the Left obviously still doesn't consider him the man in charge. Only a superhuman Machiavellian strategist could have engineered this bumbler's unlikely ascension to the presidency.
And, anyone one capable of facilitating a lightweight's rise to the highest office in the land must be not only brilliant, but sinister. For who but a sociopath would foist on the nation such a dangerous Neanderthal hell-bent on reversing the advances of "progressivism"?
The Left's underestimation of Bush and irrational fear of Rove distort their perception and drive them into a mouth-foaming feeding frenzy to devour this mad political scientist. These misapprehensions also explain their jaded view of the baseless claims against Rove in the Valerie Plame matter.
But in considering the Left's possible motives in this manufactured scandal against Rove, let's not forget the underlying subject matter driving the story: the Left's obsessive claim that Bush lied in maintaining that Saddam Hussein was stockpiling or trying to acquire WMD.
If there were such a thing as the personification and eventual death of an ideology, American liberalism would doubtlessly derive some degree of deathbed comfort from repeatedly chanting until it's final breath the "Bush lied" mantra. What began as a monstrous deception would finally ripen into a full-blown delusion where the engineers of the lie came to believe it themselves into eternity.
But American liberalism is far from dead and is eager to retrofit any available snippets, no matter how intrinsically unreliable, onto its "Bush lied about Iraqi WMD" template. One such snippet was Joe Wilson's supposed revelation that President Bush lied when stating these notorious 16 words in his 2003 SOTU address: "The British government has learned that Saddam Hussein recently sought significant quantities of uranium from Africa."
Now, let's be clear here. President Bush's statement was true when he made it, and it remains true today. The Brits made such a claim and reiterated it emphatically (with the Butler inquiry expressly validating President Bush's SOTU claim) even after the Bush-scavenging American Left falsely accused him of inventing the story.
