This is purely anecdotal, but I’m seeing a retreat among the birthers. In the old days, birthers said Obama was born in Kenya and then gave a bunch of “reasons.” Now whenever someone wants to say something bad about Obama, they feel the need to begin by the disclaimer: “I’m not a birther.” Whether right or wrong, I think the idea that “birthers are racists” stuck, and most folks don’t want to be call racists. The essential absurdity of the proposition, and the association with racism, makes it hard for anyone today to say Obama was born in Kenya, so they drop the conclusion and retreat to the reason.
I saw this “I am not a birther but…” just today on Twitter from someone who was bringing up the old saw about nobody remembering Obama from his college days. Does Mike Zullo say Obama was born in Kenya? No, he only talks about what he claims is identity theft/document fraud, a generic crime without the racial overtones. Orly Taitz is reported to have said that she doesn’t know where Obama was born, but also focuses on identity theft.
It makes no difference to me. They’re all birthers because the essence of birtherism is believing of conspiracy theory nonsense and false rumors about Obama, not the particular detail of what they say about where he was born.
