The left won’t be happy until every man, women, and child in the USA lies starving or dead.
I don’t know about the happy part - they will still see that as being unfulfilled.
The majority of the Left are incapable of being ‘happy’. They have to have a sore, a scab, something to pick at.
Let’s assume they have annihilated the Right, or picked our pockets clean to support them; they will still have something else to harp on.
It is discontent that drives them. The only dim hope is that at that point, they will feed on themselves.
