Hi,
I am the writer of the above mentioned petition. The scenario you outline is an extreme example and would not actually be possible with the guidelines for district creation that I would propose. Also, what you suggest is essentially the reality in North Carolina as we are 9/4 R/D now and will likely go 10/3 when McIntyre retires. It can't get any worse. In Texas I am told that Austin was split 4 ways to dilute the democratic vote which is the complete opposite of your scenario. My point there is that either way bad districts can be drawn.
My idea would be to have the districts drawn by having the committee start in a corner of the state and expand inward in as close to a uniform manner as possible until the district encompasses about 750k people. If a city is engulfed, so be it. If a city is split, then its influence would be strong in 2 districts, but it could not be diluted further as happened in Austin. The districts would approximate regular geometric shapes as much as possible.
Democrats would have a much better chance than they do now at a majority in the House - 1) Our ideas are better 2) Demographics favor social progressives 3) Our ever aging population favors Dems. Also, the House in general would become much more competitive and reps would have to pay more attention to both sides of the political spectrum resulting in more compromises and our national course following a more sensible middle road.
I do not think that ending gerrymandering would be the ruin of the Democratic Party, rather, if it continues, it just might ruin the United States.
Regards,
Mike
