Here is an actionable solution one that I have deployed.

Reach out to all the Reps in your sphere of influence- they are there!

Acknowledge the failings of Dems for the blue collar- this opens the door and it is true

Hear them out

Then ask them if they still want American Democracy with two parties (or three)

Stop let it sit for a week, in that week send them the Lincoln Project links.

Hope for the best
November will tell if America remains a democracy or not. IMHO
