"an attack on one is an attack on all"
That is definitely a sentiment that needs to be at the forefront of these discussions. It's where I differ with some many people. Even tho I don't generally like people, I still care about them. Which sounds weird, but it's how I feel.
Totally understand that, and that is where the erosion comes into play. Dems constantly being ready to cede ground eventually leads to the floodgates opening when the balance of power shifts harder right.
