Ayers: A Republican scandal?

Silly season is underway:

Barack Obama's campaign is citing the University of South Carolina's speaking invitations to William Ayers and Republican Gov. Mark Sanford's role as school trustee to counter GOP efforts to link the presidential candidate to the 1960s radical. . . .
In an e-mail to reporters, the Obama campaign said Ayers is a "distinguished scholar" at the University of South Carolina, where Sanford serves as the ex-officio trustee while governor.
"By Governor Palin's standards, that means Governor Sanford shares Ayers' views," the e-mail read.
Sanford rejected the argument.
"This is a totally bogus story. I've never even heard of the guy" until this weekend, Sanford said Tuesday. "This is a guy I don't know, I've never met."

Team Obama's insistence on responding quickly to every accusation, lest their guy be "swift-boated," is beginning to look like thin-skinned defensiveness. Which means the GOP should be making more accusations.
