The Obama citizenship smear hasn't gained traction in mainstream conservative circles, but this is exactly the kind of stunt the left will use to tar all conservatives and silence legitimate criticism of Obama and his policies. We need to be vociferously calling out people who traffic in this nonsense.
Scandal stories didn't get much traction during the campaign, so if we are smart, I am hopeful we won't see a repeat of the '90s opposition to Clinton, which was primarily scandal driven, and tarnished the Republican brand so that only Bush's big-spending conservatism could save it. Which is got us in the pickle we are in today.
