Even if the current story is true, which it is turning out to be a cover-up of a cover-up, its hillarious for the simple fact that her daughter is having babies out of wedlock something that Palin is staunchly against. She is a member and founder of a group that preaches abstinence and disdains childhood pregnancy.
So by "claiming" Bristol is 5 months pregnant now, which is probably is not, it does establish the fact that she is having sex, and is having sex with intent to have a baby. So this clearly is enough evidence that Trig could be hers.
Watch, in a few months the story will read, "We are sad to inform that Bristol Palin had a miscarriage". This being that in fact the whole thing is a cover story for a cover story. Notice that she does not look pregnant now when she is supposedly 5 months.
With that said, she could very well be pregnant AGAIN even! haha
All things considered, it is rotten to the core.
