Put it this way, we'd have a Senate like this (a possibility):
10 Nazis, 10 Commies, 30 or so Socialists, and the rest
Constitutionalists of one stripe or another.
it sounds good, but it is the system that the Founding
Fathers threw a revolution to get away from.
Don't be fooled.
Where does the Constitution mention political parties?
Never mind. I see the point you were making was in regard to proportional representation.
proportional representation means dozens of splinter parties left and right with seats.

Proportional representation would at least be more straightforward. Shifting coalitions already exist that are essential to getting bills even considered, let alone passed.
Tactically,this could benefit conservatives. The disparate elements of the D Party would be forced to run on their political identity, bleeding $ and support from the now-unified left. Strategically, it’s anyone’s guess, but lots and lots of open, public compromises would have to be made to form governing coalitions. The donks could lose internal control. Rafts of separate leaders would emerge. For at least a few cycles, they’ll have to fight for the easily recognizable umbrella term “Democratic”.
We can be like the Ozzies with a Pirate Party and a Parrot Party. It could be a lot more interesting, as well as honest.
