Most deceptive gerrymander?

That doesn't actually change Donnelly's district much. Makes it a point or two more Republican at most.

Not really.  It gains the Republican part of Elkhart county (like 70+% R), and loses the Southern tips that stretch into the cities of North-Central Indiana, which lean D.  It's probably a McCain district now.

I've been thinking, could you argue that states like Florida or Michigan are Naturally Gerrymandered to favor the Republican party?  I mean just in the population demographics and distribution.

I think any fairly drawn Map would benefit the Republicans in either state more than the state-wide totals would suggest, given how Concentrated the Democrats are in specific areas.

[Dgov]

Well, no. It's more that concentrated strength makes it easier to gerrymander effectively.

Well, specifically in the case of Michigan, community of interest considerations would certainly create the two Black seats and probably Sander Levin's too - though very little else of the state would look anything like it does now.

Community of interest maps would create only 1 black seat--Detroit.  They way it's split now is designed to split the 80% Black Detroit into 2 Districts to comply with VRA regulations for the state, but you can fit a district entirely inside the city easily (though the central enclaves would make such a map messy)

[Dgov]

So more like this?

That's actually a pretty even map.  the 1st, 2nd, 3rd, and 10th, would all be pretty Safe GOP, the 5th, 11th, 12, 13th, and 14th would all be pretty Safe Democrat, and the 4th, 6th, 7th, 8th, 9th, and 15th would be competitive.
