John McCain at Barack Obama's expense.
But consider a few other data points:
1) Matt Drudge hyped a photo of Obama in Somali garb that he claimed (and the Clinton campaign declined to deny) Clinton staffers had been circulating.
2) Bill Clinton went on the Rush Limbaugh show on the day of the Texas primary--after Limbaugh had spent days urging GOP voters in the state to cross over and vote for Clinton in order "rig" the election and ensure that Democrats nominated the weaker of their two candidates.
3) The Clinton campaign has been circulating an article in The American Spectator alleging that an Obama adviser, former Air Force chief Merrill McPeak, is an anti-semite and a drunk.
4) When Clinton attacked Obama on Jeremiah Wright yesterday, she did it at an editorial meeting of the Pittsburgh Tribune-Review, the vanity publication of Richard Mellon Scaife, while sitting next to Scaife himself.
Drudge. Limbaugh. The American Spectator. Richard Mellon Scaife. What exactly is it going to take before Clinton campaign staffers recognize that they are, in essence, now working for the Vast Right-Wing Conspiracy?
