It's the Rethug slime machine and the MSM that's doing it, but he's benefitting from it. I'd suggest that he take on Roger Stone in particular.
http://www.thecarpetbaggerreport.com/archives/14340.htmlYou may not know Roger Stone, but I’m sure you know his work. He is a right-wing hatchet-man extraordinaire, brazenly cynical, and free of any sense of decency or honor in a political career that began as Nixon’s “youngest Watergate dirty trickster.” Various reporters have referred to him as “a state of the art sleaze-ball,” “an extreme rightwing sleazeball,” and the “boastful black prince of Republican sleaze.” (You might notice the common thread among the decriptions.)
Stone has, to one extent or another, dabbled in at least eight presidential campaigns, including Reagan’s, Bush’s, Dole’s, and Bush’s, including helping lead street protests in Florida against a recount in 2000.
Now Stone has a new project — called “Citizens United Not Timid.” If you take the first letter of each word, you get a sense of what Stone’s up to.
And lookee here! The same asshole is being quoted in the MSM as an unbiased "source" on Obama's supposed lack of patriotism. Your move, Barack. By stomping this cockroach hard, you defend yourself and your primary opponent at the same time. Win/win any way you slice it.
http://mediamatters.org/items/200802250009In a February 24 Associated Press article about conservative attacks on Sen. Barack Obama's patriotism, staff writer Nedra Pickler quoted Roger Stone's assertion that " Barack Obama is out of the McGovern wing of the party, and he is part of the blame America first crowd." But Pickler identified Stone only as a "Republican consultant." She did not mention that Stone established the anti-Hillary Clinton 527 group Citizens United Not Timid, which emphasizes its acronym on its website and on T-shirts, or that Stone was forced to resign from the campaign of New York state Sen. Joseph Bruno in August 2007 after "allegations that he left a threatening telephone message at the office of Gov. Eliot Spitzer's father," according to an August 22, 2007, New York Times report. In a January 28 Weekly Standard article, senior writer Matt Labash described Stone as "a professional dirty trickster and high priest of political hijinks."
