If we'd had a responsible president anytime in the past twenty or so years, this insanity would have been stopped with thousands of National Guard troops years ago. But this negligence has been and continues to be deliberate on the part of presidents, many in Congress and many state officials, allowing illegal invaders to shut down parts of our National Park system.
A lot of shirkers in government would have to be replaced for this to be solved. And it would be very simple to solve.
Sorry to say, these memos were written when Bush was president. Electing RINOs is almost as bad as electing Rats.
