Heh...
Someone a while back got into a pissing contest with me about which side fields the most nutjobs. I have MANY examples.
That thing at the Rand Paul rally was the first example of anything remotely resembling Republican violence that the Left was able to find in the entire election cycle, while examples of leftist and union violence went on and on. The Left ran with it, and it didn't work. Paul won.
In fact, I was surprised that the standard Democratic shitstorm technique was a little constipated this year. Maybe there were just too many information channels.
