Dangerous kooks should not be allowed this close to ANY of the candidates.
Yes, this shouldn't be happening on either side. The Secret Service better get with it.
As for the so called "disgruntled Republican" who let them in: Somebody needs to sit the POS down and read them the riot act i.e. What are they going to say if one of these nutballs ends up hurting someone? Has the dumba$$ even considered that possibility?
That said- I do love how Mac handled it though, "ground noise and static" :-)
