As for this poll....You are likely correct. As Limbaugh might say, it is a “push poll”.
However....I don't think this poll should be entirely discounted. Obama and the question of his status as a natural born citizen is losing in the most important court in our nation: The court of public opinion.
There is NO possible way that Obama will be able to tiptoe around this stinking hulk of road kill blocking the highway to to the 2012 election.
We don’t agree often, but this time I think you are right. Obama is losing ground in public opinion, and he is likely to be asked it by people in 2012. Heck, I’d be willing to join demonstrations asking for his birth certificate AND school records! I think he owes the voters all his records, including asking Hawaii to make his birth certificate available to anyone who asks.
