But Why?

In a move widely foreseen by people paying attention, a Right Wing Nut Job has been mailing bombs to people that Trump has been demonizing from the stump.  Trump's fingerprints are metaphorically on those acts of terror.

In another predictably event, the Right Wing Wurlitzer cranked into tune and began singing their same old song: this was a "false flag operation."  False flag operations is a term for when a country flies the flag of another country to provoke a third country.  It's all very Tom Clancy.  In the context of Sandy Hook and Marjory Stoneman Douglas high school and now attempted bombings, it means that Democrats are sending Democratic icons lethal devices in order to kill them and provoke outrage.

But why?

I mean, not why would Democrats do that, because it's self-evidently crazy.  The bigger question is why that 27% of the American public who believes this bullshit would believe this bullshit. 

Some don't, of course.  I doubt Ann Coulter or Rush Limbaugh are peddling this out of deep convictions.  It's expedient and it satisfies your listeners, that same 27%.

Others have been so toxified by Fox News and the aforementioned Limbaugh types that they honestly believe Democrats are that devious and cold-blooded.  Anyone who has watched the Democratic party over the years would be surprised at this characterization.

Others have so invested themselves in their own self-righteous opposition to anything to the left of John McCain, that having their fellow travelers exposed as wannabe Timothy McVeighs and Eric Rudolphs violates their sense of their own specialness. 

The Republican Party needs to have a reckoning with their mentally disturbed and hateful base.  I'll outsource to Andrew Gillum:

The point isn't that every single Republican is a racist or a terrorist.  It's that they apparently are OK with being associated with them.
