It seems to be a weakness of our system that we cannot easily create organizations that are not stealthily taken over by leftists for their own purposes. Perhaps this is because leftists are inherently decietful. I am not sure, but we clearly need a way to prevent this kind of stealth takeover.
That and inherently obsessed with power and control. They are drawn to positions where they can throw their weight around like flies to sh*t.
It will not change the fact that the two worst recent Presidents were Democrats, and one of them when not golfing, or on vacation is the next President to lose in a giant land slide, the other one lost in a giant land slide, drools on Himself and still to this day embarrasses the Nation with His antics. There is no need for signs or protests, These two bozos speak for them selves, and accurately reflect the values and positions of their socialist party.
Note that leftists target institutions such as colleges and the federal judiciary for takeover. Once they're in charge of these institutions, they cannot be dislodged by simply voting them out, as is the case with legislative bodies.
This is the case with the Nixon Library. Although it is subject to congressional oversight as part of the National Archives and Records Administration, it will be all but impossible to dislodge the leftists who now run it--unless a new Republican administration appoints as National Archivist an activist determined to clean up the National Archives.
