Fear is the coin of the realm for the Left. They employ tactics of fear and even terror to control others. They use deception to exaggerate the nature of the danger, then they exaggerate or even falsify the effectiveness of their solutions. They in turn fear that if they are not in control, someone else will be, or even worse...no one else, and that scares them the most.
Given the record of Democrat administrations abusing their power such as with the IRS targeting conservative organizations, and the FBI and CIA's involvement with the Russian Collusion Hoax, we can expect the DHS, with their new Ministry of Truth, to also be abused also to partisan ends.
While the ouster of Trump his the Holy Grail for this cabal, their work won't be complete until Democrats are in power.
