Party control over redistricting

[nclib]

The map below indicates which party will likely control redistricting. I've used the party favored for governor and the current state legislative composition (unless anyone knows any state that is favored to flip).

Red = Democratic
Blue = Republican
Green = split
Gray = non-partisan body (or at-large)

How will this all play out?

I thought Iowa was nonpartisan?

It is. 

I put it as split since IIRC the legislature has some role - either initial recommendation or final approval. Either way, the map likely will not favor one party over the other.

And Massachusetts IS a very, very bad gerrymandering. Those districts snake all over the state on purpose so not one Republican is elected.

Actually I think they mostly do it for very different reasons (to give Worcester its own district and so on and so forth). A perfectly fair map of Massachusetts would not have elected a Republican since, say, the late 90s.

You know full well that Presidential and Congressional voting patterns are quite detached from one another.

Republicans typically do well in Plymouth/Barnstable counties.  If the likes were not too horribly skewed, a Republican could be elected to the house from that area.

Also, most Mass. house Dems have run ahead of the presidential nominee.
