Just days after PolitiFact criticized the 18% of respondents in a recent poll who believe President Obama is Muslim -- awarding them its “Pants-On-Fire” false rating -- Newsweek's Jonathan Alter offers a strong case against that and other myths and lies about the president.

In a cover story today titled “The Making of a Terrorist-Coddling, War-Mongering, Wall Street-Loving, Socialist, Godless, Muslim President - who isn't actually any of these things,” Alter goes myth-by-myth to correct the record and critique those who perpetuate it.

Our maddening times demand that the truth be forthrightly stated at the outset, and not just that the president has nothing in common with the führer beyond the possession of a dog. The outlandish stories about Barack Hussein Obama are simply false: he wasn't born outside the United States (the tabloid “proof” has been debunked as a crude forgery); he has never been a Muslim (he was raised by an atheist and became a practicing Christian in his 20s); his policies are not “socialist” (he explicitly rejected advice to nationalize the banks and wants the government out of General Motors and Chrysler as quickly as possible); he is not a “warmonger” (he promised in 2008 to withdraw from Iraq and escalate in Afghanistan and has done so); he is neither a coddler of terrorists (he has already ordered the killing of more “high value” Qaeda targets in 18 months than his predecessor did in eight years), nor a coddler of Wall Street (his financial-reform package, while watered down, was the most vigorous since the New Deal), nor an enemy of American business (he and the Chamber of Commerce favor tax credits for small business that were stymied by the GOP to deprive him of a victory). And that's just the short list of lies.

He later adds:

The blame for this extends from Fox News and the Republican leadership, to the peculiar psychology of resentment in public opinion, to the ham-handed political response of the Obama White House. Whatever the cause, if smash-mouth tactics are validated by huge GOP gains in the midterm elections, then Big Lie politics may be with us for good.

In some ways, it has always been with us, going back to the 18th-century calumny of James Callender against John Adams, Thomas Jefferson, and Alexander Hamilton. More recently, the Rev. Jerry Falwell sponsored a film that falsely accused President Clinton of ordering murders and dealing drugs. What's changed about politics as a contact sport is the reach of the lies. With the exception of Father Charles Coughlin, the anti-Semitic “radio priest” of the 1930s, reactionaries haven't generally had big audiences. But now the cranks who once could do little more than write ranting letters to the editor on the red ribbons of their typewriters (loaded with exclamation points and in all caps, of course) can spread their venom virally, with the help of right-wing billionaires underwriting their organizations. And while the cable network they watch, Fox News, might not actively promote the idea that the president is a foreign-born Muslim, it does little to knock it down. Fox often covers Obama's place of birth and religion more as matters of opinion than of fact.
