I think it's bad policy to prevent these people from hearing the President. The perception is bad, which is something he needs to minimize. If they act up, then make them leave, but they should have the opportunity to hear him. However unlikely, there's always a chance the President might sway them.
Nah, most of these scumbags like this alleged teacher Mead show up only to cause trouble.
I don't have cable TV.
On "free TV" the only MSM access I have to MY CHOSEN PRESIDENT is minimal, and obviously distorted/disjointed reporting.
I am able to adapt to rapidly changing "facts" because I have made a concerted effort to do so.
Political and/or News Junkies such as us, do our "thing" just because we want too.
We, "the people" are not an abstract concept.
