The biggest takeaway is that we may be beginning to see the alt-left collapse on itself. A whopping 43% of DEMOCRATS rated the speech favorably, as well as 71% of moderates/independents. If Trump can make it through year 2 with more progress on his campaign promises but cut out the controversial remarks, the GOP may see some big gains once midterms roll around.
That was for only those who watched. So not really indicative of a whole heck of a lot.
