Trump, like Obama before him, and like any good demagogue, has the ability to connect deeply with the emotions of his followers, rather than their minds. It seems that Trump's fans would allow him to be every bit the tyrant he's essentially pledged to be (and must be to "fix" our country outside of the constitutional boundaries of the president's powers)...as long as he delivers on his promise to secure the borders.
I've often argued that George W. Bush, whatever other qualities he may have had, was no friend of the Constitution. Chancellor Trump would be much, much worse in this regard.
If Trump wins the nomination, our country will lose in the end -- no matter who takes the general election.
