I think she’s saying: “there really is a genuine Hawaiian birth certificate. Now go focus on the stuff that can make a difference the election, like that radio interview where he sounds like the product of a relationship between Karl Marx and Chairman Mao.”
but that requires actual work and effort.
My belief is that the average voter would be less likely to vote for someone who hides his birth certificate than by listening to that radio recording. The average person would not even understand what is being said, I don’t believe, and would just push it in one ear and out the other. But hiding something as simple as a birth certificate....that would make them wonder...would make them pause.
