ABC has released the first of what will surely be many promos for the multi-platform (GMA, Nightline, World News, and 20/20) ratings-grabber that will culminate in Barbara Walters' interview with Sarah Palin on Friday. It's basically going to be Sarah Palin week. In the promo, Sarah confesses that she and First Dude Todd had no idea that their daughter Bristol was sexually active until they found out she was pregnant. If you watch closely, when Sarah says "truthfully, we were devastated" she looks like she's about to cry after all.
