Nah, this isn't like the stuff the conspiritards come up with. As whoever wrote it says,
In this scenario, we don’t want to marginalize the more extreme candidates, but make them more “Pied Piper” candidates who actually represent the mainstream of the Republican Party.

They used the last half-century of Republican strategy against them, but they didn't force Trump on anyone.
