"The way I told my members: It's like telling your friend the guy she's dating is a jerk."
I have to say that this strategy is better than treating voters like they are racist, sexist homophobes. Hillary had a few more insults in her deplorables speech but you get the idea. No, this isn't that bad but it's almost as bad.
They'll be patronizing voters with a "we know what you need better than you do" attitude. That's certainly not unusual for Democrats but people don't like to be patronized. In fact, that's one of the reasons they lost these voters in the first place. Democrats really need to get their head around the idea that people who didn't vote for him knew what they wanted and Democrats weren't offering it. If you want to win their vote you need to offer them a vision that'll make their lives better than what the Republicans offered.
They shouldn't assume the voters will turn on Donald Trump. Hillary Clinton made her major selling point that people should vote for her because Trump was a horrible person. That didn't work well. Yet Democrats can't seem to get their heads around the idea that some Trump voters supported him and still do even after all the revelations. The polls are saying they aren't disappointed.
While some people will vote Democratic because the President disappoints them, there were many people who didn't vote for Trump who still voted Republican down ballot. So these people already didn't want Trump.House Republicans had more votes than Donald Trump, while House Democrats had 4 million fewer. So disappointment with Donald Trump might not be enough of a sell.
If Democrats don't give people a reason to vote for them and just hope people do so to vote against Trump, they may be disappointed with the election result. Again.
