[Florida Man for Crime]

Here's a Democratic gerrymander of the Virginia House of Delegates, using the same 2020 Population Estimates data as I used for my VA congressional maps in the other 2020 redistricting thread I made a while back.

It is designed to make it very difficult for Republicans to win a majority and also to give Democrats a favorable chance at a supermajority (at least in good/neutral years), and thereby rig elections/politics in Virginia in favor of Democrats and against Republicans.

I didn't bother trying to draw any R+ districts that might be able to elect Conservadems, although there are maybe 1 or 2 places where that could be possible on occasion.









I am not going to bother trying to differentiate which district is which. Doesn't really matter. The Dem ones are Dem, the Rep ones are Rep. Instead, I will focus on the stats of the districts and how the stats overall work together.



Here are the districts sorted from most Democratic to most Republican by PVI. The numbers mean 50 + Dem PVI. For example, the most Democratic district is 75.98, which means it has a PVI of D+25.98. The most Republican district is 20.59, i.e. R+29.41.

The 51st most Democratic seat is D+8.32 and the 67th most Democratic seat is D+4.25. So Democrats just need to win every seat that is D+4.25 or higher to get a supermajority, and Republicans have to be winning more or less everything that is D+8.32 or lower to get a majority.

96   25.68
97   24.46
98   23.76
99   22.51
100   20.59

On a graph, that looks like this:



The thing you can see from this is just how stark the drop is between the 69th most Democratic district (D+2.32) and the 70th most Democratic district (R+11.03). So Republicans are packed and cracked pretty thoroughly. The 10 or so very most Democratic districts that you can see are more Democratic than the rest are basically all in inner NoVa, where there are no remotely Republican precincts anywhere nearby that they can swallow up. Every other Dem district is involved in some way or other in cracking/packing Republican voters.



As far as racial stats goes, I didn't look at race data at all when drawing the lines, only political data. However, here is what the districts look like when sorted from lowest White population to highest White population, so there ends up being a pretty decent number (23) of majority-minority districts, and also with quite a few additional districts where minority voters would be the de facto most dominant political influence:




Also, all the Dem districts voted for Obama in 2008 by a margin of at least 4 points higher than the statewide average of Obama's win.

That’s a devious Dem gerrymander of VA, there. Well made, even if I doubt they go that aggressive
