Betcha super don will say it was the Dems who sent the pipe bombs to make him and his jolly band trumpicans look bad. Wanna bet?

That has been floated..not by President Trump but others. Given that none seem to be made to actually work. 
It could be a way to motivate the Dems for midterms. 

Personally, I doubt it. Cause that person would have to be will to go to prison for a long time. 
I have a theory on how targets were chosen. 

We will have to wait until they catch the crazy before we know anything for sure.
