Here is Steve Shannon in his own words on why he wants to be Virginia's attorney general and why he thinks he is going to win. What it comes down to is that he does not see the attorney general's job as a stepping stone to promotion of any social agenda, liberal or conservative. He sees it as a job protecting Virginians from lawbreakers, including Internet predators, payday lenders, gangs, and sexual predators who prey on children.
