All a recount does is check the math. If vote fraud occurred, those fraudulent votes will still be counted.
I think she is smart to take this stance at this point. There are plenty of indications of incompetence and conflict of interest at this point. Fraud is harder to prove than incompetence at this point. If she starts screaming fraud from the get-go (even if she thinks it has been committed), she can be more easily dismissed as a kook. She doesn't have the luxury of emotional and knee-jerk reactions without proof in hand like those on Free Republic do. She has to be methodical and exhaust every legal recourse.
You and I both know there were shady dealings behind this election, but she's the one that has to fight the fight.
