Greg Combs, a recent PhD from UT Dallas (and fellow Sleestak fan), has assembled one of the coolest political iPhone apps I've ever seen. It's called TexLege. Basically, it's just a really sophisticated directory of the Texas state legislature. It's far better than any app I've seen for the national government, and I don't know if any other serious apps exist for state legislatures.
The upper screenshot at left shows the main alphabetical listing of legislators. Note how each line shows you the name, the photo, the party, the district, and the number of years of service. Plus, you see that red-blue bar with the star? That's an estimated ideal point derived from legislative roll call votes. How cool is that? That's a lot of of information displayed in a very economical way.
The lower screenshot shows the entry for one particular member. Here we get to see a comparison of the member's ideal point with those of the two major parties over time. Scroll down further and you can see which committees he serves on, contact information, an interactive district map, the Votesmart profile, and other things.
The version of TexLege up on the App Store right now is a bit outdated -- Greg has been letting me demo the new version. Unfortunately, I believe he plans to ask $10 for the new one. Still, I'd imagine that a number of lobbyists would be okay paying for that -- this could be a very valuable resource for them.
I wonder if Greg would be willing to partner up with some other state legislatures or the NCSL to export this technology beyond Texas.
