The left is definitely not giving up. That’s probably why they’ve been far more effective over the last few decades than their actual numbers would imply. The left still holds many levers of power. I’m sure Trump is no dummy. The left will make nice if necessary (against a powerful foe) so long as they keep moving the goal posts to the left. What we need is a leader who forces them to reach across the aisle to the RIGHT for a change.
Their numbers indicate that there were more leftists/Hillary voters than centrists & conservatives/Trump voters; no reason why they should give up...
The Left will scream if you attempt to slow leftward movement. They will go into hysterics if you attempt to halt leftward movement for a while. They will go into rage if you attempt to reverse Leftist gains.
The lesson from this, is that if they are going to scream anyway, you might as well “go big”. Like Machiavelli once said, “do not do your enemy a small injury”. Do things to permanently cripple their power. I remember the screaming in Wisconsin when Scott Walker and the WI Republicans fought to pass Right to Work. It was a long and bitter fight, but the result was a permanent crippling of one of the Dems main bases of support.
Trump needs to do similar things : identify things which will permanently cripple the Dems, and go for them. Eliminate government unions.
Slash funding to leftist universities. Etc
The left is still far too entrenched in both local and national government bureaucracies. For too long, both parties have been big-government advocates who have left us with entrenched civil servants faithful to the leftist cause. Elections don’t get rid of those folks. The swamp is deep, and wide.
