Agree with many of the recent points. Here is what I think the Democrats need to do.
They need to focus on one theme over and over and over: the fact that Republicans are lying about everything. And attack their “news” sources relentlessly.
And then point out fact via fiction over and over on every single issue, as a quick side note, not a main focus.
Hammer the lying theme home for the next 3.5 years relentlessly, and nothing else. Forget the “working family” crap, “the rich paying their fair share”, and every other tired message that has failed to resonate. Attack the root cause - the truth and lying. Attack them. Don’t say things that can be attacked. Win the crowd. Win the election. Win the mid-terms.
Conversely, I disagree strongly with the strategy of ramping up the far left progressive messaging in an attempt to draw in new voters. Why? Because the election showed us that young people are more complicated than just wanting progressive government. They’ve shown they also can be victims of disinformation. And important segments of those potential voters do have real concerns about the overstepping of the government for minorities, and other issues. For example young professional white males need to be won too. Trump’s campaigning brilliance was saying things that appealed to every potential voting segment, including racists, nationalists, etc. While the Democrats shouldn’t lie like Trump, or target unsavory segments, they should also not alienate large voting segments.
