The irony of your image of Reagan calling on Obama to tear down this BarryCade... The Reagan Library is shut down, you can not enter it. The exception is the Air Force One exhibit which is budgeted separately. Typically, they charge a fee to enter the plane, but for the duration of the shutdown of the library, they are letting people into the exhibit for free.
The people are forbidden from entering the library itself and seeing the portion of the Berlin Wall on display, or some of the ironwork from the World Trade Center. Our President, doing the job that terrorists and communist regimes failed to do.
