apparently Trump is following some of Nixon's playbook.
Nixon shut down the mexican border in 1969.
unlike trump, Nixon did this very early in his 1st term.
I think he will do this in the next 6 months to 1 year. More likely, I think he will do it next year as a campaign tactic.
He has telegraphed what he intends to do early on by doing a feint by threatening to do it and backing off and follows thru it months later.
