Considering that this police state installation is being done by a regime who actively refuses to enforce immigration laws and attacks any State government who does try to enforce them, the goal is clear. USSA here we go.
The other thing to take into consideration is that the DHS was created under GW Bush our illustrious GOP president. So don’t look for the GOP to push for controlling TSA or the DHS. They love power as much as the progressives do. I used to believe that the GOP would save us from this encroaching tyranny but now I think only CW2 or some kind of a grid down situation will be able to shake things up enough to get the average american off their duff and ready to restore their freedoms. For all intents and purposes we have already morphed into a more sophisticated version of the USSR.
