Bringing facts and logical arguments to that group is a waste of effort.  Every action from them is calculated to gain them their end goal.  I am convinced by their actions that the ends justify any means.  These include ommission, obfuscation, fear, deception, personal attacks, subject changing, false premises, and even outright lies.  You can spend all you time and energy clarifying all these incorrect points only to have the administration shift the argument once again so that you have to start all over without ever making a dent on there direction or focus.

They are very careful (clearly by design) to craft communication so that it is difficult to cite them in an outright lie within a short time period.  Any time span longer than a week gets considered as "under different circumstances" and previous statements are curiously no longer valid in any rebuttal argument.

This behaviour is not usually acceptable between individuals or businesses because it destroys trust in any future dealings.  But for some reason this has become the dominant political model in the U.S. and we allow it to exist at our peril.
