Jonathan Pie explains it

[Undertoad]

The "emotional group" was the left, who wanted to hear so they could hate;

And they predictably emotionally overreacted to each of these things in turn, hence actually promoting them to the people who kinda liked the ideas, and leaving no air in the room for anything else.

And this is one reason my question "What would you say was Hillary's most memorable, popularly repeated and heavily debated policy proposal?" ...got crickets.

Thus allowing the Trump campaign to have messages that were far stronger and more widely spread than the opposition, even as they were outspent two to one.

Who elected Trump, YOU did.
