ummmm....the Democrats have 59 Senators.
For now. Which is why it won't be used to force anything through. Not only would that violate a precedent
the Republicans themselves refused to cross when they had power (for fear of exactly this reverse situation) it would just pour even more fuel onto a mass defeat what, 8 months from now?
Live in fantasy worlds if you like, but this is the reality of the current state.
And as a larger political/philosophical issue, no, there is nothing respectable whatsoever in a 51% bare majority being able to do whatever it wants with legislation, no matter how massive or intrusive.
Touting 51% as a simple (and often transient) majority as the Holy Authorization Of Anything is touted by the power-hungry as a Good Thing because, go figure, without it, their power lessens.
I suspect some readers will go apoplectic reading that, meme defense mechanisms will engage, and they will regurgitate memes whose purpose is to downplay that and up-play "anything goes", in an attempt to defend their overmeme that seeks to spread itself via force, i.e. legislation. To take on the civilized propriety of discussion to ultimately mount a very physical forcible spread of ideas.
