you totally dismiss the fact that the party that is legislatively in power every decennial , controls the congressional redistricting maps.
The minorities have been squoze out, diluted, and massively disenfranchised in the three key "purple" states, by creating these fractionated gerrymandered electoral districts .
Theres a good book in the making about what happened in Chester County in 2016. It went DEM, first time since Cleveland and it was due primarily to the rapid population growth in upper income hispqnics nd blacks(its the richest , highest educated county in Pa and it was sooooo red till 2016.BUT, the power of the county's growth was watered down by breaking it up and diluting this electoral punch by creating these really bizarre legislative districts.
This is "real rigging" nd the Trump team mined that by addressing its coalition of whites in the districts it could affect.
Smart, but hould be considered unethical and criminal for the future
SO, please don't try to make the case that we even are close to a fair representation ala "one man one vote"
Im as critical of the Dem gerrymandering (like Md and NY) also.
