This is not out of character for Paulestinian suicide bombers.
Since they know they can not win, they are happy to strap on the vest and take as many down with them as they can.
True Paulers hate social conservatives as much as they hate the inside the Beltway GOP. Their goal is take over the GOP by 2016, by marginalizing both sides of the party. They figure if they destroy both sides and get them fighting with each other, the take over will be complete.
