Basically in Chicago, Trump's enacting one of Obama's legacies, but to make it palatable to the Tea Party and to Red America, he's framing it as aggression against Blue America. If Trump pulls off this bluff, Red America has finally accepted ramifications of the 14th Amendment that it's resisted for over a century
Uh, what? Last I checked, the National Guard call-up and enforced desegregation in Little Rock, AR happened on order of President Truman, who was a Republican, and incidentally had a VP by the name of Richard Nixon.
If you're going to cite Republican opposition to the CRA in the 1960's you need to do some better research. The Republicans objected to it on grounds that you would see echoed today by many others who also are not racist(although many may accuse them of being so): They made what would now be considered "The Libertarian Argument" today in regards to what the CRA was doing. They didn't feel the Federal Government had, or should obtain, the authority needed to enforce many of the provisions contained within.
It also ignores that if you check your history books, many of the "Red States" of today were states that were helping push and support many of those same Civil rights reforms that happened in the mid-1960's and earlier. They haven't been fighting against Civil Rights for the past century. They've been fighting against what the Civil Rights Act did, starting in the 1960's with the quotas.
and Trump gets credit for what no one will remember was Obama's plan to save Chicago from violence. BUT IF TRUMP's BLUFF FAILS, then Chicago becomes the epicenter of a race war.
I doubt a race war is going to break out. Well. I guess I need to walk around that a little bit: I doubt a race war is going to break out so long as "outside agitating agents" don't insert themselves into the mix trying to "create the optics" of one happening. We have more than a few generally left-leaning groups that are not shy of employing such tactics, and those allegations have been made in regards to more than a few of the "riots" that have struck in other communities--That the people who initiated most of the violent acts/heated language, and in particular the ones doing most of the looting and burning, were not locals.
Basically they found a time/place they could get to(by whatever means) where they could cause some mayhem and stand a good chance of getting away with it, so they took full advantage of it.
This is also partially our new reality in the age of Google Maps/Google Street view, and other such things, such as aerial camera drones and what not too. Even that "Street tough" can whip out Google Maps/Street View and use that to "get the lay of the land" for where they're heading long before they ever go there. If they have some well heeled backers, they could even send someone through with a Drone-Cam in advance and potentially "scout things out" in advance when they know they're dealing with a "heated situation" that is likely to play out over several days giving them time to plan.
We're no longer dealing with the days of "simple" street riots like happened even as late as the 1990's, where most of the rioters actually were local to where they rioted.
Further hampering things is I'm sure the media is going to absolutely jump on any chance they get to try to report anything they can as racially charged/motivated so they can gin up that same "race war" narrative in the interest of pumping up their ratings.
Not going to argue on Mexico, as you probably have it about right.
