People often picture a tsunami as a towering wall of water slamming into the shore, as in the movies "2012" or "Deep Impact."  

Generally, that’s not the way it works. Instead, a tsunami is like a super-tide, rising so fast that it can engulf you in minutes, if not seconds.  

And the water is a tsunami usually isn’t normal sea water. It’s filthy sludge, filled with debris.  

And that is what we are going to see between now and November on our TV screens and web browsers: a fast-rising tide of filthy, sludgy right-wing propaganda, threatening to drown us all. Dirty Money.
