JMHO
When he was doing his drone filibuster (2014? 2013?), I happened to be on the Internet and it closed down. Completely. Not just Twitter and Facebook. The overload was too much, as happens to a lesser extent at peak usage times now and then.
He has enormous hidden popularity. Unfortunately for him, as you said, lack of attention breeds more lack of attention.
I’m not a Rand Paul supporter, but he provides a media lesson: The media create their own reality. It’s only natural, for who can be satisfied with just reporting what’s happening? That’s like being the secretary at the board meeting. They lust to have an actual effect on the real world, and the only way they can do that is by lying and otherwise distorting the truth.
