Spin is normal in politics, but Romney is pioneering a cynical strategy of reducing fact and truth to pure partisanship.

Granted, presidential candidates are no strangers to disingenuous or overstated claims; it’s pretty much endemic to the business. But Romney is doing something very different and far more pernicious. Quite simply, the United States has never been witness to a presidential candidate, in modern American history, who lies as frequently, as flagrantly and as brazenly as Mitt Romney.

Now, in general, those of us in the pundit class are really not supposed to accuse politicians of lying – they mislead, they embellish, they mischaracterize, etc. Indeed, there is natural tendency for nominally objective reporters, in particular, to stay away from loaded terms such as lying. Which is precisely why Romney’s repeated lies are so effective. In fact, lying is really the only appropriate word to use here, because, well, Romney lies a lot. But that’s a criticism you’re only likely to hear from partisans.

This is perhaps the most interesting and disturbing element of Romney’s tireless obfuscation: that even when corrected, it has little impact on the presumptive GOP nominee’s behavior. This is happening at a time when fact-checking operations in major media outlets have increased significantly, yet that appears to have no effect on the Romney campaign.

What is the proper response when, even after it’s pointed out that the candidate is not telling the truth, he keeps doing it? Romney actually has a telling rejoinder for this. When a reporter challenged his oft-stated assertion that President Obama had made the economy worse (factually, not correct), he denied ever saying it in the first place. It’s a lie on top of a lie.

You really need to read the whole (short) piece to absorb the magnitude of Romney’s brazen lying, and to understand the complete and utter failure of the American pundit class and national political media to do their job of informing voters about not just what a candidate says, but what is the objective truth.
