This is why democrats are credibly accused of creating and using rent-a-mobs and why professional protesters never seem to have jobs they need to get back to doing. Protesting IS their job.
And they are dumber than stumps. Jesse waters interviewed several and the dumbasses didn't even know what the hell they were protesting.
That's just it, the protesters don't have to know anything. The ones paying them don't want to advance an idea, they just want disruption and chaos. They want the headlines to be about the fight, not what the Republican actually had to say, and I expect this to become SOP from democrats. Any time a Republican or a conservative gives a speech, he/she should expect disruption and chaos from democrats trying to stop them from speaking.
