There is reason to believe that there is some imbalance of representation on the margins due to things like gerrymandering, and the effect is probably a couple percentage point difference than what they should be.

Other than that, the vast majority of identity representation in government appears to closely matche identity of voters.

Also, I am not comfortable talking about it like this, because I believe it is bad thinking and possibly racist. I'd rather we have a bunch of white people vote for Tim Scott instead of us getting bogged down in the poor thinking that there is some positive that comes from people voting based on identity such that demographics of representation reflect demographics of population.

That strikes me as being identity motivated, and I'm not into thinking like that.
