Well at least we now know what she was thinking:
Speaking to the conservative talker Rusty Humphries today, Sarah Palin left the door open to speculation about President Obama's birth certificate.
"Would you make the birth certificate an issue if you ran?" she was asked (around 9 minutes into the video above).
"I think the public rightfully is still making it an issue. I don't have a problem with that. I don't know if I would have to bother to make it an issue, because I think that members of the electorate still want answers," she replied.
"Do you think it's a fair question to be looking at?" Humphries persisted.
"I think it's a fair question, just like I think past association and past voting records -- all of that is fair game," Palin said. "The McCain-Palin campaign didn't do a good enough job in that area."
