IMHO - Sadly, I think Trump is too late with this address. Trump needed to use the “bully pulpit”/national addresses on this issue LONG ago. The Dems/Media have been pounding their point of view home for over 2 years. They are way out front on this issue.
As Trump tweets to his base, almost every media outlet has run negative “border wall/barrier/fence” stories morning noon and night under the guise of “news”. CNN/MSNBC don’t really offer the news per se. What passes for news programs are nothing more than political talk shows containing propaganda designed to present/reinforce the Progressive agenda.
This sorry state of affairs, coupled with the Corey Gardener and Susan Collins wing of the “Blue State” Repub Party in the Senate, along with other so-called Repubs inclined to undercut Trump and the security a barrier would afford in order to keep their seats secure in 2020, and the easily manipulated electorate who knows more about the Kardasians than their government, and an education system/entertainment media (Hollywood and TV) in near-complete control of the Left leaves me to think any hope of a serious barrier being erected is nothing more than a pipedream.
As for Trump’s threat to declare an emergency along our southern border as a means of extracting the funds necessary to affect barrier/wall/fence construction - forget it. Dems would immediately run to the 9th Circuit Court Of Appeals. An appellate judge would issue an injunction halting the whole process… Let’s face it, the 9th Circuit and the Left runs the country.
Republicans, most specifically, “The Turtle” - Sen. Mitch McConnell - still haven’t figured out the only chance for funding and building a meaningful barrier along our border - one that would actually assist our border patrol - evaporated with the ending of the last Congress when the House, controlled by Repubs could have sent a real funding bill to the Senate and where McConnel and Senate Repubs could have changed Senate rules allowing for passage with a simple majority of the Senate.
I fear McConnell’s allegiance to an arbitrary, self-imposed “process” and not border security will eventually render what political conservatism is left in this country, outnumbered and irrelevant within the confines of electoral politics…
One day - perhaps fairly soon - there will be a Dem POTUS and a House and Senate in the hands of Dems. When that happens, 60 votes in the Senate be damned - you can bet the Democrats will not miss their chance to make millions of “new citizens”/Dem voters.
