Because Roy Moore is not of The Swamp. If you are not of The Swamp, you are a threat to The Swamp. Reminds me of a classic Star Trek episode ...
You are not of The Body Swamp!
And the funny thing is that there are Landrus (landrieus) in power in Louisiana.

Ah yes, the Star Trek episode with people who were controlled by Landru, who was a computerized entity. People were absorbed by Landru. They behaved in a robitic manner except for periodic “festival” when they went wild.
