President Donald Trump’s obsession with our southern border is because he made the wall his principal major political issue in getting elected. On countless occasions, before and after his election, he promised it would be built and amazingly made the ridiculous claim that Mexico would pay for it.

As a consequence, we now are in a horrendously harmful and needless government shutdown, all because Mr. Trump desperately needs a wall victory so as to appease and maintain the core supporters of his political base. He knows that, without them, he has little political future.

The plain truth is that we have four borders: Mexico, Canada, the Atlantic Ocean and the Pacific Ocean. The easily accessible public records covering our many years of struggling with illegal imports and illegal immigrants clearly show that most illegal activities involve the ports on these ocean borders. This evidence shows that if a wall was made to totally block our Mexican border, it would hardly make a dent in the illegal traffic coming into our nation.

Our only national emergency today is having a president who is willing to do anything possible to ensure his own political survival, willing even to affect more than 800,000 federal employees with a shutdown.
