Can you tell me which Trump policies were pro-labor, pro-union, pragmatic, positive visions of the future?
There was none.
It turns out that actually you don't need pragmatic, positive visions of the future to win. In fact, we have plenty of evidence that pragmatic policies at all are a massive electoral liability when facing someone who is, again, willing to simply lie about everything.
In Trump, you have clear evidence that people do not need pragmatic solutions to anything. Somehow you are pulling from that the conclusion that Democrats are not pragmatic enough.
What makes you believe there is public appetite for pragmatic solutions? Enough to win a national election?
Trump does not offer real solutions, except as a sound bite in passing (to be later ignored). But in the absence of pragmatic policies that voters can get behind, the winner will always be the candidate who offers to tear down the system that has failed the people. Mark my words.
