Recall:
1..The fake telephone conversation from 20 years ago where he impersonated his PR person.
2..His opening statement on June 16th when he called out the flood of Mexican coming across the open boarder.
3..His 3 page tax returns form years ago that showed a loss of some $900 millions.
Basically he throws some Non-PC statement out there and the MSM and Dims jump all over it. Subsequently he hits them with the truth and/or uses their statements against them.
Its an adaptation of the Thatch Weave tactic.
