If true, (and that is a big if) this story would be explosive. At the very least, with this rumor circulating in Alaska prior to her pick, this story gives some insight into how poorly McCain vetted Palin.
All we know for sure is that in the photo’s of Palin at the end of her second trimester, she does not look the least bit pregnant. However, I don’t think Palin should submit to a paternity test.
I am not one of those who follow the logic, “If she/he has nothing to hide? Why Not?” It strikes me as deeply unamerican to have to prove your innocence like that.
