It's from the Washington Post, but it gives the general idea pretty well.
What it has led to is, instead of electing a representative for all the people, we are now electing a racial or partisan favorite.
He didn't say this, but I think once the process has started, it feeds on itself and gets worse.
It might be better to just draw straight vertical and horizontal lines instead of trying to make sure every group gets a congressman.
California is the poster child for exactly that. As a conservative in Silicon Valley I have absolutely no representation at any level of government from the Governor on down to the local school board. All of those people are essentially communists proudly wearing the "progressive" label.
The Republican party has become a "rump" party here; they have no say in any state legislation. The urban and suburban areas have maybe 20-25% conservative populations. (San Francisco County voted 85% for the Bag)
The only good news is that the major land area of California in the "outback" counties are almost all run by conservative Repubos, but the population of those counties is not enough to run the damn Rats out of state government.
