Republishing note: As there are a lot more maps here than there were in the first minutes when I posted this diary for the first time, I think that it is worth a re-post.
Recent additions are the Congressional Maps for Arizona, Alabama and Maryland, and something redistricting geeks will love -- an almost complete dataset for the Congressional Maps that were used for the 1988/1990 House elections. I'm saying "almost" because California is mostly missing-- it crashed on me when I was mostly done, and I was so frustrated by that that I didn't continue working on it until now. I included the last save state of my DRA file, which unfortunately is just NorCal.
Now that a lot of redistricting maps at all levels-- Congress, State Legislatures, local-- are complete I thought it would be a good idea for the redistricting community here to work on getting the official maps into the tool of our choice-- Dave's Redistricting App.
I started a GDocs folder to collect these maps, but I'll put the links to the maps themselves in this diary as well, and update as more maps come in over the next weeks.

Other maps by me
The 20,000 deviation between Virginia's 2nd and 3rd Congressional District's are due to the State of Virginia considering the precinct Zion Grace to have a population of about 20,000 more than DRA does, and the adjacent precinct Taylor Elementary School (both Norfolk) to have 20,000 less.
Oregon's State House districts are nested into the State Senate Map (1&2->1, 3&4->2...), but for some reason I can't get that into DRA's head, it refuses to load the State Senate map for me-- but as you can see, its information is contained in the State House map.
