The Trump Flip Flop Reminds Me of a Local Election I was Involved In.
Let me see if this analogy works. My Dad was a City Councilor in our home town. He ran "At-Large", meaning city wide, in a city with 21,000 eligible voters at the time. The 5 top vote getters of the at-large council candidates would win. In this particular year, my Dad was running for re-election. The big fight in the town was that a long term, incumbent Mayor had a challenger in an equally long term State Rep.
One of the other incumbent Councilors decided to get involved in the Mayor's race, and endorsed the current Rep against the incumbent Mayor, and put a bumper sticker on his own car. I should note here that this was a 50-50 race at the time. All the Mayor's supporters turned against the councilor who took that stand. Shaken and politically frightened, he retracted his endorsement of the Rep and declared his neutrality in the race. Dumb move. In the first instance, he alienated everyone on one side and his corrective action alienated everyone on the other. In the end, he lost big. By the way, my Dad won one of those seats.
The point here is Trump has staked out the bigotry side of the immigration issue. Now he is measuring that he can't win with just the bigots. Conway, a pollster, has explained that to Trump. So now, Trump's going to try to pretend he's not a bigot by flip flopping on his bigoted anti-immigration stand.
In the end, he'll end up just like the City Councilor who tried to fool all of the people, all of the time. It just won't work. He'll end up losing both sides.
