Those are not "principles." Just saying.
They are "positions" on Political/Economical issues. Principles are what a person believes and will not compromise...........it's called Integrity. Of this, Trump is "void." Void means ......."zero, zip, zilch, nada!"
Now, Trump's idea to "secure" our Southern Border will not work. JUST building a wall will not secure our Southern Border, and I assure you, when and if this wall is built, it is we, the American Tax Payers who will pay for it, NOT Mexico.
As well, ALL of the Candidates are in support of securing our Nations Southern Border, so, that is not a reason to vote for Trump in and of itself.
IF "principles" are the qualification we are looking for in a President, then we had better look far away from Trump.
