This has always been the biggest fear of the anti-Trumpers. That all those they have successfully brainwashed against him will start to come around on him once he gains office and actually starts getting things done that are good for America.
That "protest" we saw on Saturday around the country was extremely well organized and timed to gain maximum participation as anti-Trump feelings were still running strong. All the stops were pulled out to gain maximum impact in a desperate attempt to "kill" the Trump presidency while it was just coming out of it's womb.
With that massive protest, they shot their full load and they came up short.
From here on out, President Trump will continue to win folks over and Saturday's big protest will be seen as the "high water" mark for anti-Trump sentiment.
However, locked/loaded will be prudent in the interim.
