First amendment sucks, doesn't it?
It has nothing to do with the First Amendment, as you should know. It has everything with SP tantalizing her fans with the possibility of a run, but not getting into the fight and joining a debate where you have to raise your challenges face to face with your opponent(s).
If she decides not to run, she can attack to her heart’s content. In the meanwhile, she’s playing the fan base and attacking from a safe distance. I don’t see political sniping as particularly courageous nor an attribute of leadership.
